HP OfficeJet 3830 Review
HP OfficeJet 3830 Review. The HP OfficeJet 3830 is a jet A4 multifunction sober ink that the brand intended primarily to micro-businesses that print relatively few and do not want to ruin at least for purchase. We'll see why! Sold around 65 €, the OfficeJet 3830 provides printing, scanning and copying, as well as fax. Its flatbed scanner available for this purpose a dedicated paper entry allows easy faxing multiple pages. Connected, it incorporates a module Wi-Fi 802.11 b/g/n (with Wi-Fi Direct feature) but has no Ethernet port. It also lacks automatic duplexing and does not offer a card reader.

In ergonomics, if everything is broadly in line with what must offer 4-in-1, certain points deserve as attention here. For example, from a "pro", note that the paper feed tray on the back is not a drawer and accepts a standard sixty sheets (80 g), which can be detrimental knowing also that there is no second tray to store another type or another size paper.

A document feeder is present for easily faxing several loose pages
The driver and setting via a monochrome touch screen of 5.5 cm diagonal not always very responsive and quite small, which does not facilitate certain operations such as scrolling. Perhaps would it have been appropriate to complete this screen several classic buttons. Despite this, the use of the printer is intuitive and if we hesitate in any proceedings, it is possible to read a little streamlined video support. Updating the firmware  is a breeze, but it is pity that we should always ruin a sheet (and ink) for complete network information.

Thoo small screen to do everything
The printer size is pretty standard for this type of product (450 x 364 x 224 mm 5.6 kg). The build quality is generally reassuring, with plastics that look solid and that can not hold too fingerprints, except at a bright area around the screen. Some alignments lack a little precision, but it remains on the finishes absolutely correct in that range. However, it is somewhat disappointing that the paper tray does not open by itself when launching an impression, and it is roughly two hinged plastic tabs which, for once, really are low end.

Two ink cartridges, one for black and one for the three colors
No rocket science in the procedure for replacing the ink cartridges (HP 302 or 302XL): just open the lid and make the change. The back of the printer is very bare, showing only the paper tray and, in terms of connectivity, the power connector, the USB 2.0 Type-B and two telephone sockets for fax.

HP OfficeJet 3830 The defends pretty well, with flow rates measured at 12.8 pages per minute (ppm) in black and white and 8.6 ppm color. In a range of price and close to a level of functionality roughly equivalent, the Brother DCP-J562DW up to 15.4 ppm in black and white. In color, the flow is almost identical (8.7 ppm). By cons, it is clear that a more printer facing domestic use including the photo, such as the Canon MG5750, rest going away from this level of performance black and white, with a rate of only 5.6 ppm, that it counteracts with 10.5 ppm color. Overall, the OfficeJet 3830 is a good average. Regarding office print quality, it is a good level, either black and white or color. The texts are perfectly legible, either on white or colored background; we distinguish well enough gradients in the graphics, although we've seen better. The accuracy is good and the ink does not bleed.

The scanner of the OfficeJet 3830 is a model that works up to 1200 dpi, 24-bit A4. This is a flatbed scanner that makes scanning books and other bound documents. Its specific paper feed can scan / fax number of loose sheets in a row. The scanner is fast, allowing to scan an A4 sheet at 100 dpi in color in just 11 seconds. And it takes only 20 seconds for a photo 10 x 15 at 300 dpi. It's a little better than what the Brother DCP-J562DW. This is also the case in copy area in which the OfficeJet 3830 shows its advantage over most of its competitors. It must indeed him 14 seconds to copy a document in black and white and 21 seconds to perform the same task in color. In comparison, a home printer such as the Canon MG5750 is slower, and even much slower in color.

HP OfficeJet 3830 Review

The OfficeJet 3830 is doing quite well even if it is obviously not their first use. To the eye, the result is in any case very clean. It must be enough against a patient, knowing that it is necessary to wait 1 minute and 19 seconds for a photo print borderless 10 x 15, and 3 minutes and 42 seconds for an A4 print. Color Rendering The displays a delta E average of 7.9 which is between two waters. The OfficeJet 3830 is thus more accurate than a printer oriented "pro" like Brother DCP-J562DW (average dE 11), but it is exceeded by the capabilities of most talented in photo printers like the Canon MG5750 (dE means 4.4). Remember, the limit at which the eye is not able to detect a color difference is below 3. The largest color differences are measured on the magenta (10.3) and green (10, 2), while the pale red or yellow stand out so much more faithful.

Ink Consumtion
With only 1 W in standby and consumed mainly 7 W in operation during a photo printing, OfficeJet 3830 is one such model. Few printers to be as energy efficient. The noise emitted at the printing is very acceptable to his hand. Our sound meter placed near the printer has risen from 45.6 dB (A) values ​​on a standard printing and 43 dB (A) on a photo print. Loading paper is not much noisier, and these are of course the rollers that move the paper is meant the most.

Cost per page
This HP OfficeJet 3830 works with HP 302XL cartridges or 302. It ships with starter cartridges whose capacity is limited. HP cartridges 302 black and three colors have a particular print capacity respectively to 190 and 100 pages. HP 302XL with higher capacity are obviously more interesting, with 480 and 330 pages data capabilities. Sold at the official price of € 28.90, they can print at a cost per page measured at 14.8 cents. That's a lot, well above the average cost per page of A4 multifunction (nearly 9 cents). It is probably for this reason that HP intended primarily this model for micro-businesses that print very little, between 100 and 250 pages monthly. However, this is one of the main flaws of this printer.

HP OfficeJet 3830 Review

Note that the HP OfficeJet 3830 is compatible with the HP Instant Ink program, a program that consists of a subscription invoice from € 2.99 per month to ensure to always have a good level cartridges with ink but limits the amount of printing 50 pages per month (with credit to defer up to 100 pages). This will drastically reduce the cost of printing the page (which happens to 6 cents), which is cost-effective when you print at least 19 pages per month. By cons, we continue to pay even if you do not print, and if it cancels the subscription, the cartridges stop working. To book those who print regularly so. On and ready to print, the HP OfficeJet 3830 offers eight seconds to get his first black and white page. On waking from sleep, the same page takes 14 seconds to print. A time going up to 28 seconds when the printer is off.

Final Conclusion
The HP OfficeJet 3830 just misses the 4 stars. We do not blame him as his slight weaknesses photo that cost the really high page. Its ergonomics are left entirely out of too small touch screen not responsive enough, and some details of finish contrasting with a product yet also reassuring. It loves against its connected features that take advantage of the built-in Wi-Fi module, speed in classical office tasks (printing, but also scan and copy) it performs perfectly, and its low energy consumption.

Test Fujifilm X70: presentation and characteristics
Fujifilm is not his first attempt in the expert compact segment with a large sensor. Everyone remembers the X100 introduced with much fanfare at the photokina 2010  and versions X10, X20, X30 with sensor 2/3 ". Unlike most of its competitors (the Sony RX100 Mark IV, the Canon G7 X Mark II or the recent Nikon DL ), Fujifilm has not made ​​the choice of a sensor 1 "but has developed a compact expert with APS-C sensor. X10 / 20/30 will they have a successor? Hard to say, but the Fujifilm X70 more like X100 without its hybrid viewfinder system so unique.

The X70 includes all the main features of the X-E2S: APS-C X-Trans CMOS II 16.3 Megapixel sensor and EXR II processor, a new hybrid autofocus system 100 000 px phase detection with fashions "AF Area" and "Wide / Tracking AF" on 77 points, an auto macro mode, digital rangefinder, the function focus peaking , film simulation modes and Wi-Fi. the screen of the Fujifilm X70s' directs up to 45 ° down and 180 ° up. For this new housing, Fujifilm has chosen a 28 mm focal length (the same as the Ricoh GR II or the Nikon Coolpix a); a more complex lens to use than the more conventional 35 mm that the brand seems to reserve to the X100 series. Optics is also less bright f / 2.8 against f / 2.

The Fujifilm X70 was launched in February 2016 at an RRP of € 799. The X70 therefore has a little "wobbly" position: It has no optical zoom manual makes the interest of the X10 / 20/30 and has not built a covered X100. He will have to rely on other assets to seduce.

Epson WorkForce Pro WF-R4640 EcoTank All in One

No comments :
Epson WorkForce Pro WF-R4640
The Epson WorkForce Pro WF-R4640 EcoTank All-in-One is an expensive printer, but provided with a large capacity ink, and high-capacity replacement cartridges are very economical. One of the continuing complaints that our readers are about printers is the high cost of ink. With EcoTank printers, the WorkForce as ET-4550 EcoTank All-in-One and now the WorkForce Pro WF-R4640 EcoTank All-in-One, the price increases Epson printers but provides them with an enormous capacity ink. Furthermore replacement cartridges also offer a cost per page very low. The WF-R4640 is the top model of multifunction printers inkjet range EcoTank and these models will allow significant savings to your business with low operating costs of these products, but only if your volume monthly print is high enough.

Design and features
The R4640 can print, copy, fax and scan. It is large for an inkjet MFP with its dimensions of 51.3 cm x 66.3 cm x 65.5 cm mode, for a weight of 23.8 kg. The paper capacity is 580 pages, divided into two paper trays 250 pages on the front and a feeder 80 pages at the back. On top, the two-sided 35-page automatic document feeder ensures scanning, copying and fax.

The printer driver configuration is slightly different from conventional ink jet printers due to the design of the cartridges, which are rather bags of ink cartridges, similar to medical pouches for liquid to be administered intravenously. After shaking each bag twenty times, they fit into the bays on each side of the printer - black ink on the left and three ink colors right. It remains then to attach the handle of each bag in the receptacle provided for this purpose to lock. The installation is easier than for the other EcoTank printer we tested, the ET-4550, for which to pour the contents of the bottles of ink in printer pools. You can Download Epson WorkForce Pro WF-R4640 Driver Here.

The WF-R4640 can be connector to a computer via USB 2.0, or a wired LAN via Ethernet or wireless with Wi-Fi 802.11 b / g / n, or by direct connection to a computer or a mobile device through Wi-Fi Direct. It also supports printing from mobile Epson iPrint for iOS and Android, as well as from Epson Email Print and Epson Remote Print which both allow users to automatically print documents by sending email. Epson provides the ability to assign an email address to the printer during setup, which you can modify to your liking.

Printing performance
We evaluated the performance of the Epson WF-R4640 on our panel of professional applications (using the hardware and software tools QualityLogic for measurements), and measured lightning speed of 10.3 pages per minute (ppm), equivalent to the speed of the Epson WorkForce WF-4630 Pro (10,2ppm) and slightly better than the one we selected as Editors' choice, the HP Officejet Pro X576dw (9,5ppm). It is very much faster than other multifunction EcoTank we tested, the ET-4550, we had measured 3,8ppm.   The WF-R4640 takes on average 46 seconds to get a photo 10x15 cm, compared to 41 seconds for the Epson WF-4630 and 26 seconds for the HP X576dw.

Print Quality
The overall print quality was a bit lower than inkjets. To summarize, it is good on the texts, slightly down on the charts and in the middle for photos. Text quality is quite satisfactory for conventional professional prints, but perhaps not sufficient for important documents in terms of sharpness.

The graphs show a little saturated colors, with bright colors. Several areas of color exhibited a phenomenon of banding (streaks on the graph). Very thin colored lines are barely visible on two illustrations of our testing. The photos are generally of a similar quality to that you can find in the supermarkets bounds.

Operating cost
According to traditional measures (with the price and performance of high capacity Epson cartridges), the WF-R4640 allows very low cost operation, with only 0.9 cents per page in B & W and 2.4 cents per page in color. But this applies only to replacement cartridges because the printer initial purchase price plus the price of ink. The supplied cartridges worth € 480 while the printer is rated at 720 €, considering the total price of 1 € 199.99 for R4640. This is € 320 more than the audience of non-EcoTank version of the printer (model WorkForce WF-4640DTWF).

Final Conclusion
This WorkForce Pro WF-R4640 EcoTank All-in-One Epson is a great multifunction printer offering exceptional speed and PrecisionCore printing technology. It comes with enough ink to print two years and covered by a standard 2 year warranty.

+ PLUS: Supplied with ink for 20 000 color and black and white prints. Cost per page very low. Total paper capacity of 580 pages. Duplex Scanner with 35 loading pages. Automatic duplex. Full connectivity with Ethernet, Wi-Fi and Wi-Fi Direct. Good quality text printing.

- MINUS: high purchase price for the printer. Slightly below the average graphics printing.

* PRICE:  € 1199

Fascinating accessory for photographers: Ricoh Theta S in Test
The Ricoh Theta S is a compact full-sphere camera that records both photos and videos in the 360-degree panorama format. Coupled with your iPhone or Android smartphone you think so firmly the environment. We have m15 looked at the successor of the Theta accurate and reveal the detailed review whether it is worth buying. The Theta S is already the third member of the full spheres cameras for 360-degree images of the Japanese manufacturer Ricoh. This has the models reproduced with improved facilities. The current top model promises significantly improved practicality and quality as even the predecessor Theta m15. Whether the switch or the new acquisition for you worthwhile to clarify the following lines.

Design, processing and handling
The design of the Ricoh Theta S is simple. The soft-touch finish on the front and back provided an enjoyable and quite safe stop. Hemmed the camera in a plastic frame with metal finish. Here is the not entirely convincing workmanship is visible. If you exert some pressure on the frame, these are to some places and reacts with an unsightly cracking. On the side we find three buttons. They are used to turn on and off, the activation of the WLAN module and to change the recording mode. These have, in contrast to the button for triggering crisp pressure points. The trigger is for a somewhat smooth and the other has the play button. Because the two lenses protrude on both sides of about half a centimeter, you should be very careful in handling the camera so as not to damage the glasses when depositing. At best, you stowed the Theta S after each use in the supplied protective case.

On the front you will informed about the current operating mode with different LED icons. Interfaces include a mini-HDMI output and a MicroUSB port available, invite her over the camera as well as video and photos to your Windows PC or Mac can transfer. On the top we find both microphone and the speaker of the Theta S. The latter is only a shutter sound on its own, which you can not disable.

Features and functions
The Ricoh Theta S has two image sensors in the 1 / 2.3 format, which dissolve each with 12 megapixels and composed for pictures with 14 megapixels care. Videos succeed in Full HD resolution (1,920 x 1,080 pixels) at 30 frames per second. In the previous one had to with 6.4 megapixel photos, and a maximum of 15 frames per second satisfied when shooting video. Furthermore, Ricoh has extended the maximum length of video of 3 to 25 minutes. The lens has a maximum aperture of f / 2.0. In addition to the main functions for recording 360 degree videos and photos, the Theta S can also be used for the live streaming video via the HDMI interface.

The internal device memory amounts now no longer to four but eight gigabytes. That is for 1,600 images rich in full resolution as well as 65 minutes of full HD video manufacturer. A microSD card slot for expanding the memory we were looking at the device, unfortunately in vain. The permanently installed battery promises about 260 photos on a single charge. Our test was able to confirm this value roughly. For the creative freedom Ricoh offers mobile apps for iOS and Android.

With this you can, among other things, see the live image and make various shooting settings. So you can manually define, among other things, the light sensitivity (ISO) or the exposure time. The shutter speed can be set between 1/6400 seconds to 60 seconds for night scenes. For these long exposures are not blurred, a tripod mount is installed on the underside, which is compatible with all standard tripods. If you want really deep dive into the 360-degree images, can switch on the mobile apps during reproduction in the so-called VR mode. In this, the image is divided into two parts for viewing with VR goggles like the Google Cardboard reproduced. The orientation of the field of view then follows the movements of your head.

If one has the Theta S liberated from its package, you can start in theory directly after switching - select desired recording mode and press trigger. The little flattering Shutter subsequently confirmed taking a photo or the start of a video recording. But what now? The camera does not have a display on which you can watch your videos or pictures.

1. Smartphone connectivity
Before their pictures or videos of Theta S with your smartphone or tablet PC can look, you need first the app "Ricoh Theta S" for Android or iOS. After installation, first the coupling of the camera with your smartphone or tablet via Wi-Fi needed. For this you have to press on the camera and then register you with your smartphone on the wireless network of Theta S the corresponding WLAN button. The password takes you to the bottom of the camera. It is made ​​up of all the numbers that are shown on the small print. The password can you change at any time in the app settings. The range of the WLAN, we noticed positive. Who does not want to see as a photographer in the picture may be a bit move away far from the camera and use the phone as a remote shutter release.

Are you connected, you can start on your smartphone app. About the home screen of the app you reach the menu item "Camera". Click her to seeing you all stored images in the camera are displayed. Here you can now individual photos by tapping on or more transferred to your smartphone via a long press and marking. Optional can move their images or copy. The menu item photos reaches its your Gallery - about "App" can be found all already transmitting photos.

Fascinating accessory for photographers: Ricoh Theta S in Test

About the theta symbol in the lower options bar you reach the recording mode. Use the arrow keys you reach the various modes for shooting. Here are "Manual", "Automatic", "Shutter priority" or "ISO-priority" to choose from. Furthermore, you can perform a manual exposure and adjust the white balance of the environment. About the upper right menu icon you can select the live view mode, view the memory status, and the battery level of the camera. For more editing options of your photos, the manufacturer offers additional apps. With this you can, for example, filter over your shots Laying, make cuts or make multiple recordings for a motion effect. Overall, mobile applications looked a little unfinished. We also had to occasionally find a certain instability of the connection between your phone and camera.

2. PC connection
A second option provides the transfer and viewing of video and photos on the PC. For this, you must first connect to the Windows PC or your Mac only the camera via USB cable. On Windows, the Theta S is displayed as a normal storage device. Under OS X you have to turn off the camera and hold before connecting to the Mac both wireless button and the shutter release button. Subsequently, the Theta S should also be recognized on the Mac as a storage medium. Now you can draw on the computer you your files via drag-and-drop to a desired position.

To view transferred photos and videos on your computer, you have to get the appropriate software for Windows or Mac to download and install . Although the files in the usual JPEG or MP4 format to be created - for 360 Play the additional software is necessary. After the start you can simply pull in the main screen of the Ricoh Theta desktop software or locate photos via "File"> "Open" and then start to view the previously copied files via drag-and-drop.

Before playing videos need to be converted for the Panoramic view which assumes the software fortunately fully automatically. Then you can while playing with the mouse and the mouse move freely in the recordings. For zooming you use the mouse wheel or alternatively the zoom icons on the screen. Practical: Have you multiple photos copied to a folder and open one of them, you can watch using navigation buttons in the display mode of desktop applications throughout folder forward or backward move. Optional their photos can also easily and without prior editing in Google Photos Upload. The online service recognizes the 360-degree images and displays it after the upload to the corresponding all-round view. So you can watch the images then also share comfortably on scale collections with friends or acquaintances.

Image quality of the photos
In terms of image quality you are allowed because of the small sensors in commercial compact cameras are used, of course not expect miracles from the Theta S. In good lighting conditions, the camera delivers in automatic mode from decent picture material. If you zoom ride to individual image areas, however, the rather small detail sharpness of the images is noticeable. Even with the color reproduction and the dynamic range, the Theta S struggling. With less light the automatic mode is only limited, not to use up. At higher ISO settings, the images tend to excessive noise, textures and details blurred completely.

Fascinating accessory for photographers: Ricoh Theta S in Test

If you still want to get in appealing images even in low light conditions, the manual mode via the connected smartphone and use a tripod or stable subsoil recommends. then selects the ISO speed 100 and additionally a long exposure time. In Live View mode, you can make some assessment of the resulting image. Triggered is then via the mobile device. The image is then automatically transferred to your device for viewing. What works well: The camera is retouched both videos and photos out - they can not be seen on the photographs.

Image quality of the videos
In the field of video you can you choose between two resolution variants. Full HD (1920 x 1080 pixels) or HD (1080 x 720 pixels). Who rejoiced in terms of video quality on genuine Full HD, will be disappointed. Due to the extreme expansion of the image sections of the moving images work on larger screens dissolved significantly lower than photos. Here you have to get adjusted to significant drawbacks compared to usual high-definition video. This is sometimes at a relatively low data rate, which leads to compression losses. Nevertheless, the opportunity to move via mouse and scroll wheel freely in the fully spherical shots a fascinating effect. The optical quality could have been here already clear quality.

Social media
About the desktop applications and smartphone apps sharing photos and videos is possible via social media such as Facebook, Twitter and Tumblr. However, the parts is effective on the Ricoh own website Theta360.com on which ye have to register with Twitter or Facebook account. The upload of the image or video is on the Ricoh website. In Facebook or Twitter only links that then lead you for viewing on the Ricoh website appear.

The optional parts via Tumblr, is only possible via the desktop application. For integration on your website, you can click on the theta website an embed code to retrieve. For the necessary data protection the setting makes "unlisted". Better does it work via Google+. If you upload a picture here, the viewer can optionally switch on the Photo Sphere icon in the 360-degree view and thus also move about the mouse gestures freely in the image. To upload 360 degree videos on YouTube, we need only the already described transmission and conversion procedure of the camera through the computer. Then you can upload the files on YouTube, which are then displayed in 360-degree mode. For the viewing of videos, the web browser is Google Chrome needed. Furthermore, you can get your shots on the Google Street View app share with the world. For this, you simply navigate to the "private" the Street View App. Now you can either selected individual images or upload directly automates all 360 recordings.

Price and Availability
The recommended retail price is 400 Euro. At this price you can find the camera currently at different online merchants or retailers

For that reason and with other companies in the industry created a name Internet.org initiative whose main objective is the one mentioned, give everyone a basic service that they are able to surf the Internet. Keep in mind that according to a recent study published in February by Internet.org only 40% of people in the world connects at least once a year to the Internet. uneven Percentage if we divide developing countries, 29.8% and developed, 76.2%. Match these figures is the target drones Facebook.

Mark Zuckerberg, founder of the  social network, just announced that it will form the drones of Facebook with which Internet.org will facilitate connection to the network of the most isolated areas . In the words of Mark itself: The final design will have a size of wings larger than a Boeing 737 but will weigh less than a car. You will receive energy from solar panels on its wings and have the ability to stay at altitudes above 18 kilometers per month.

The drones Facebook used to help 10% of the population living in remote areas and do not have the necessary to surf the Web infrastructure. It is similar to Project Loon of Google that wants to put balloons at high altitude with a similar purpose. Obviously Facebook wants in this way to increase its figure of 1.4 million users. No doubt that is an interesting project.

Drones Qualcomm, the future of the Snapdragon?

Qualcomm drones. The drones are one of the gadgets that are attracting more interest for quite some time. What for some is a simple toy, for others it is a tool with which to fly away their working material. More and more used in the world of professional photography and even as distribution, the proof is that Amazon has already made ​​some flights to deliver goods.

The chipmaker Qualcomm has shown interest in adapting their products to these devices. A drone with brain Snapdragon? It may be the big news of 2016. Qualcomm wants to bring improvements to the drones. Qualcomm has announced its interest in improving the drones and provide them with components. It will be at CES 2016 when we can see the early work of the manufacturer, but have already passed us something to whet your appetite. The aim of Qualcomm is twofold: to significantly increase flight range , currently too low, and lower the high budget same. Getting a drone with 4K recording for $ 400 could soon be a reality thanks to this manufacturer.

Drones Qualcomm, the future of the Snapdragon?

Also they improve the cameras and the new drones would endow more varied sensors to make a more complete experience of flight . In this sense, not only the resolution of the image would be improved, also bypassing of obstacles and even better could have a dual camera. To do this, they have created the Flight Snapdragon platform with everything a drone needed to be better. From the chip to the chambers, through connectivity.

The world continues to progress and improve drones and 2016 may be the year of his final takeoff. We look forward to bringing you all the news from both Qualcomm and other manufacturers to enter fully into this fascinating world.

Bebop Parrot Drone, analysis

Parrot Bebop Drone. When we talk about drones a major commercial manufacturers is Parrot. The French take a few years and launching air quadrupeds and third generation raised Bebop Drone better flying experience and give more prominence to the camera with a set of powerful image stabilization. A lot to talk but are a gadget worth to have a look? Parrot still betting big on the category with affordable models but now analyzed to see if they are still up to it. We put our table analysis to take flight. Before the Bebop speak Parrot Drone, we teach you video so you can see what he can do and the quality offered by your camera. If you are not very familiar with the sport, it's a good way to know through this video. At first glance Parrot Drone Bebop may give a misleading sense. It looks fragile but appearances are deceiving. The body is sturdy and the plastic pieces that hold the propellers protectors do their job very well. When we missed flying and hit the ground first check that indeed this drone is hard. Light, the weight is concentrated in the body where the battery and the camera goes. Removable parts are easy to manipulate so put them back in place or we will change shortly. Setup is simple and put into operation for the first time will take very little time.

The system used to attach the strap is simple but very effective. A piece of Velcro around the body of the drone is responsible for securing to the vehicle chassis. A physical connector, slightly hidden in the housing to prevent damage, is responsible for the energy reaches the central system. The battery is removed in an instant, but then we have to make sure that is well tied not to move.

The drone comes with spare propellers if they break when we're flying. At the time we've been testing, it was not necessary to replace them despite the many blows he has taken during the analysis. With guards in place, Bebop Drone drone proves to be a robust enduring good falls. When the drone is on and takes a few minutes running, be careful when you pick up off the floor and we take the body. It tends to become very hot, enough to notice that bother hand but not enough to burn. Unless strictly necessary it is always best to leave it off and let it sit for a moment.

Regarding the design few drawbacks can be removed them. It is a simple drone, light but solid and when it offers no problem using it for the experience. The pieces are placed quickly and ease of use encourages anyone, regardless of their ability, want to use.

Fair performance and battery
To use the Parrot Drone Bebop we have two options, either to manage virtual controls in our mobile device or with a physical control that is sold in advance of publication that has taken Parrot. In our case, we have analyzed the most basic model and we controlled the drone from a mobile phone.

For synchronization Parrot has a mobile application also in charge of communication between the vehicle and our device through a WiFi network, also it serves as a guide to learn how to use, accessing lessons to learn to fly and view multimedia content we have been recording. The application works well and the connection is immediate. In fact, if we do it manually (via the Settings menu wireless networks) took less than if we let the Parrot app takes charge of the work. Once we have synchronized just have to give the button off to be off the ground.

At this point we have three controls ranging from a basic to an advanced passing through an intermediate. Each offers a different way to move the drone and this is where we should have a little patience because the interface is not quite intuitive and we will take a moment to understand well how it works and what to do to bring the Bebop Drone. By default, we will find a number of limitations and high speed but we can modify them to go a bit faster and reach a height of 50 meters. In principle, it is legal to use the drone in Spain but take care to avoid problems.

Controls may end up being frustrating if we have patience, physical control is a useful option but quite expensive prices drone. Another problem when using it is so low that the battery lasts. Each load is 11 minutes of use (approximately), fortunately comes with an additional but if we take the day playing with him and you know that you can not do it for more than 20 minutes in total.

The 14 megapixel camera that incorporates not only allows us to see through it but record images for later viewing. The quality offered is exceptional and is similar to that offered some action cameras like Sony Action Cam. Of course, something goes behind GoPro for example. The great success in this regard is the image stabilization. No matter if you turn or do tricks with the drone, the camera does a great job with image stabilization. Of course, if you expect professional results, you may want to look at other drones that are on the market. The camera offers good results but bright image usually noisy, frustrating if we try to do something elaborate. You can forgive them that much but with the price that the quality offered is very fair.

A drone for a few, the opinion of Techbild
There is no doubt that the drones are an attractive category, invited to play with it and let's try that but are justified in the 600 euros cheaper version? It is a huge barrier to entry if we only want to browse and introduce him in the category. If we are to give an exhaustive use, within the limitations of the battery, it is a good choice. However, if your interest is limited experience with the product and see what it can offer, you may want more make a smaller investment and satisfy your curiosity. Parrot has a good product but is in between leaving a little cold: very expensive for those who want to dabble, and unambitious if we seek something with greater pretensions.
