Evoluent VerticalMouse 4 VM4SW Wireless Mouse Small - Right Hand aka VM4RSW

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.
Improved thumb rest
The thumb rest has been reshaped to provide even more comfort over earlier versions.
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.
Adjustable optical sensor
Pointer speed controls on the side allow convenient adjustment without even releasing your grip from the mouse.
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).
Mini Receiver
The tiny 2.4 GHz receiver avoids being knocked off the side of a notebook computer.
