I use this with a pc plug into the tv . sit on the couch from across the room , the wireless aspect work great . here be a few thing I really like about the keyboard : the trackball be easy to use the `` mouse '' button for the trackball be well positioned and have several option . there be a handy left-click button on the edge of the keyboard just under the trackball . it be very well position for how I hold the keyboard . likewise the scroll wheel on the left edge of the keyboard be in the perfect place to use it . and there be two other left\/right mouse button on the main keyboard surface . the keyboard be a nice small size but will full size key . more equivalent to a large laptop keyboard than a desktop keyboard . I do not want a big keyboard sit by my tv and this fit just right . the only downside I have see be : there be no indicator light -lrb- numlock \/ cap lock -rrb- on the keyboard . that be a real problem when log in . I understand they probably omit the light as a battery power save feature but I really think they be necessary . really minor here : the wireless receiver dongle be larger than I would like . it be stick out of a front usb port on my pc and I would really appreciate a smaller receiver so there be less chance it could get bump and break .
