I purchased this item to work with Raspbmc on my brand new Raspberry Pi. Worked straight out of the box. Plug and play,. No drivers needed. The functions take a little getting used to, especially because there are no instructions for them, and i'm not sure all the keys work. After a month am still finding that out. But it does what i need, and all the basic functions you need from a wireless remote are easy to find.
plug it in and it works, no fussing with installing stuff. Does exactly what I need it to do, plus a bit more. I cant figure out how to program the 4 hotkey buttons though. I dock it one star because of the instructions - minimal, broken translations of english. Works on windows 7 (64bit).
