My main purpose in getting this was to use with a laptop, but problems start to arise once the laptop heats up a bit, the heat seems to affect the little USB receiver and you start getting glitches.
After only a short time of use, the keystrokes frequently don't register. If you're typing away and don't look at the screen, you look up and then have to go back over the whole text to type (several times) the letters that didn't register the first time.
The other thing is that, although the wireless mouse works and feels great, it goes through batteries like a water through a sink. Of course, depending on use, you'll be going through expensive AAA batteries about once every week. Simply not economical or convenient (having to make sure you have a plentiful supply and/or rushing out to get more once you've run out). Couldn't the designers have thought of some sort of rechargable battery built in to the mouse? Recharged through a USB port docking station or something for ease of use?
A few months later and I've finally decided to throw it away. Can't even be bothered sending it back...
