we use this for we linux base dvr system we build and absolutely love it . we have be fight with a normal size keyboard and mouse for year that the range on it be terrible . sometimes we would have to be right up to the area where the emitter be for it to work . this thing be nothing like that . it have a great range , great battery life , great feature . you can turn it off when not in use . the touch pad be small but definitely get the job do . it be a perfect size for sit on you desk or end table to easily control a computer from afar . nice and easy to type on too . pro : - Perfect small size - great range - on\/off switch - rechargable - long battery life - Works with Linux - include specialty and function key - backlight ! con : - none so far !
