Kensington’s SlimBlade Mouse with Nano Receiver is the perfect travel companion for your laptop. Sleek and thin this cross-platform work horse fits seamlessly in your hand and in your carry-on. The plug and play nano receiver is small enough to keep installed in your computer or conveniently tucked away under the battery cover. The laser sensor enables precise control on numerous surfaces and the 4-way tilt scroll wheel is the best we’ve ever used, especially at $39.99. The low battery indicator was an unexpected blessing midway through my trip!
