Aesthetically I find it very successful.
Installation: You must click on the "connect" button below it and the device is recognized. Ok for my PC running Ubuntu (linux) and OK for my android 4.2 tablet (position of the keys in English keyboards, but it is the fault of android that does not offer the French layout. Personally the English layout "blind "I do).
I put 2 AAA rechargeable batteries. I prefer the batteries because the batteries when the batteries are worn out I could change what is not possible with a battery.
Size: Small! and for me that is a huge plus because I can move the keyboard closer to my body and thereby stand upright on my chain (my back told me thank you). Note that the difference between the keys is the same as on the main keyboard which allows comfortable typing.
