this be a great purchase for I . the device itself be slim and small enough to keep it with rest of the remote control . I use it operate a computer connect to my hdtv and it work great from about 12 foot away . tap on the mouse pad or scrolling by run the finger on the pad sometimes do not work as great while the device be hand hold - I generally place it on the arm rest for more stability for these operation . overall it have make life so much simpler for not have to worry about a full size keyboard and mouse lie around in we living room but still get the full use of the hide computer .
