Additional Detail for VerticalMouse 2

Eliminates Arm Twisting

The patented shape supports your hand in a relaxed handshake position that eliminates forearm twisting. You will quickly become accustomed to the improved comfort. An ordinary horizontal mouse requires your forearm to twist away from its natural position.

No Retraining

The grip is the same as an ordinary mouse, just turned sideways, and the buttons are operated by the same fingers. There is virtually no retraining necessary. The mouse does not move sideways when clicking with normal force. Pointer control is as accurate as any other good mouse.

Fast Response

1200 dpi true optical resolution sensor reduces hand movements. Great for games. (Other mice have 800 dpi)

Easy Clicking

The button force is light for easy clicking, but still firm enough to avoid accidental actuation.

Programmable

5 buttons -- 4 are programmable with 59 selectable functions each with Windows driver, plus special features such as:

• Vertical scroll - press a button and drag the mouse to scroll with greater precision and control than the scroll wheel.
• Auto click - automatically perform a double click by pausing the pointer.
• Click lock - press and hold a button momentarily to simulate continued pressing without holding down the button.
