I buy this because I Thought it would be nice to use on my media pc because it be the size of a remote control . first thing I notice be that the laser point do not work at all . advertise that it have one . I do not need it but if you tell I it be go to have one I expect it to work . that be the first clue about the quality of this . then I use the keyboard after fully charge it and with direct line of sight this would not work right to keyboard or mouse . combine that with the small mouse pad and keyboard and you have to get up and point the device to get it to go more than 10ft away . end of story I return this crap quality device for a small logitech k400 unit a bit larger with full size keyboard and trackpad build in . it work perfectly from around 20 foot away -lrb- all I test -rrb- and the device work perfectly with my Mac pro , linux box , Mac Mini , and Gateway laptop . great handy keyboard to have lay around . just pop the usb dongle in and both mouse and keyboard fire up . this mini piece of junk I have to return .
