This is a well designed, fully functional, sturdy little device which I use to control a laptop hooked into my TV from across the room. I sit about 20 feet from the PC, and the bluetooth works fine from that distance. There is no interference from other bluetooth devices in the room, nor does it interfere with wireless controls or devices. The buttons are well placed, as is the scroll pad and mouse pad. I haven't figured out a good way to click and drag yet, but I'm sure there's a convenient way to do this as well. Very nice little item, at a good price.
