Cordless Optical Trackman full review
More rat than mouse, the Logitech Cordless Optical Trackman is a big, beefy alternative to traditional mice. Built with comfort in mind, the ergonomic design feels more like a bed on which to lay the palm of your hand.
It’s a feeling, along with the lizard eye optical trackball, scroll wheel and various buttons, that takes a significant time to master. Your patience, however, will be rewarded. The more time invested, the more the Trackman feels natural and intuitive, with real potential to relieve RSI symptoms.
