Evoluent VerticalMouse 4 Right Hand Mouse VM4R is an advanced revolutionary mouse that amazingly relieved wrist and arm pain. The shape has been further refined in subtle details based on the ergonomic lessons learned from the previous two generations.
Comfortable and easy to use. The shape is thoughtfully sculpted for uncompromised comfort and easy-to-reach programmable buttons. No finger contortions are needed to operate the buttons.
Adjustable optical sensor. Pointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse.
Improved thumb rest. The thumb rest has been reshaped to provide even more comfort over earlier versions.
Mini Receiver. The tiny 2.4 GHz receiver avoids being knocked off the side of a notebook computer.
