Looking for a 3D-capable Media Box I landed here at TizzBird F20 4G Media Player. Previously I used a Popcorn Hour A210, but although a bit older could all except 3D format. After much searching I found one here on Amazon. While I was thinking only of a Popcorn Hour A300 or A400, which have all but done badly, because I ended up at the TizzBird F20, with very good reviews. Somewhat skeptical, I then ordered him and can say that I have not regretted the purchase now. The box is connected with me via Ethernet with a NAS and HDMI on TV. When streaming of major formats incl. 3D, there were no crashes or delays. Amazing is the picture and sound quality, both were on my old box is not as good. Especially the 3D streaming is awesome, very good transmission and quality. Although this is not the latest version of Android, the software scope is considerable. What can be downloaded via APP missing. Surfing I would, however, not on the box, this then you need a mouse or keyboard with trackball or touchpad. Surface is easy to operate and does not require deep knowledge of Android. Even the look of the box no standby makes a good impression, it is small and passively ventilated and also has a reasonable cut-off, (adjustable). For me, the really only significant drawback was that I did not get formatted on the software of the box hard drive that I have built. Here I had to format with NTFS disk on Windows, after which it was recognized in the box. For someone who has no PC, but only a notebook that can be exciting. Since then helps only a USB external disk connection or acquaintance with PC. Updates can now upload the new firmware directly through the box via the Internet. All functions here describe is beyond the scope of this review. Hence my conclusion: A box with very good price performance ratio, as well as many opportunities. Suitable for beginners and advanced.
