Using the Belkin MiniWireless Optical Mouse feels a bit like mousing with a 16-stick pack of gum. It weighs just 2.9 ounces and is roughly half the size of competitors. To get it that small, Belkin made sacrifices in both the comfort and convenience categories. You can forget about the MiniWireless Optical Mouse filling your hand--for most people, all you'll need is two fingers to hold it. Though the mouse is obviously targeted at travelers, its tiny size makes it impossible to store the wireless receiver with it. The receiver itself is not much smaller than the mouse, making it one of the largest receivers for notebook mice. It's also one of the worst performers we've seen, barely keeping a connection with the mouse at just less than three feet away.
