Evoluent VerticalMouse 4 Small VM4S 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.
Pointer speed indicators.Top mounted LEDs show through the chrome thumb rest to indicate selected pointer speed including extra low (XL), low (LO), MD (medium), to high (HI).
Now two thumb buttons. A new bottom thumb button provides greatly extended functionality when used with the included driver.
Extended lip prevents rubbing. An extra wide lip along the bottom edge prevents the last finger from rubbing the desk.
Powerful and intuitive driver. Evoluent Mouse Manager provides extensive but easy to use functionality for 6 buttons through a simple and intuitive interface.
