Kensington SlimBlade Trackball Mouse review
With minimalist styling, a gunmetal-grey finish and no visible buttons, the SlimBlade oozes quality. It feels great in the hand, too - the rounded contours are backed up by a reassuring weight. But what lifts it above other Bluetooth mice is the ball on the top: double-click the area just below and the SlimBlade switches from standard to trackball mode. Why? One obvious example is if you're making a presentation - rather than bend down every time you want to move the cursor, use the trackball. It works well in practice, and there's no need to load up any software. The only downsides are a high price and the fact no Bluetooth adapter is included in the box.
