I was amazingly surprised. It is simply an android tablet version 4.4.2 on his TV. The remote control uses mouse and keyboard appears. This was inconvenient but I could carefree connected keyboard and wireless mouse. From there, the navigation has become easier.
Clearly, this smart box with Andriod BOX written on it (notice the reverse i) does the trick. I downloaded an app in the Play Store (file explorer) and I could have access to those of my freebox, computer and even my android phone!
The total area is about 5GB but can install an external hard drive. This is not a lightning war but helps out greatly. No slowdown observed. it's pretty fluid.
For the price to take. As a main box I would say no, but typically in a room that's largely the case!
