The patented shape supports your hand in an upright neutral posture that generally avoids forearm twisting.

Features:

• Wireless
• Size Medium/Large (for hand lengths at least 178mm. Suggest DATA5250 for smaller hands)
• Right handed

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 Pointer Speed

A button behind the wheel enables quickly changing the pointer speed to suit different tasks: select higher speed (higher DPI) to make the pointer move faster for general use; select lower speed (lower DPI) to make the pointer move slower and more precisely for drawing, photo editing, etc.

Pointer speed indicators

Up to four lights show pointer speeds from slow to fast: slow speed or low DPI for precision work such as photo editing or drawing; fast speed or high DPI for quickly moving across the screen for general tasks.

Mini Receiver

The tiny 2.4 GHz receiver avoids being knocked off the side of a notebook computer.

Powerful and intuitive driver

Evoluent Mouse Manager provides extensive but easy to use functionality for 6 buttons through a simple and intuitive interface.
