On the desk, the 800dpi optical mouse worked flawlessly; we didn't experience any glitches in cursor movement or loss of signal. We had no problem establishing the connection after our PC was restarted or when it woke from sleep. The only trouble we had was mastering the swipes, which work by pressing the large middle navigation button to show your programmed commands, and then performing a swift slide or flick of the mouse in the appropriate direction to execute the desired command. Shakes (moving the mouse quickly up and down or from left to right), desktop hot spots (corners or sides of the screen that, when selected, perform a programmed command), and the programmable buttons all worked flawlessly, although it took some practice swiping and shaking the remote to get the commands to work. The mouse is nearly as easy to use in the air as on the desk, and it works up to 30 feet away from the receiver; however, it responds better to quick flicks of the wrist than to subtle movements, making precise control a bit difficult.
