Evoluent VerticalMouse 4 Small Wireless, Oikeakätinen, Vaakasuuntainen muotoilu, Optinen, Langaton RF, Musta, Ruskea

Avoids forearm twisting for comfort and good health
The patented shape supports your hand in an upright neutral posture that generally avoids forearm twisting. Many users, including medical doctors, ergonomists and physical therapists, said the Evoluent VerticalMouse provides superior comfort and even relieved their wrist pain.

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 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.

Improved thumb rest
The thumb rest has been reshaped to provide even more comfort over earlier versions.

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.

Now two thumb buttons
A new bottom thumb button provides greatly extended functionality when used with the included driver.

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

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.
