Say goodbye to wrist pain
The Scroll Endurance by J-Tech Digital is perfect for anyone who experiences wrist or hand fatigue when using a regular mouse. Its vertical design reduces the torsion of the forearm and wrist caused when using most other mice. The Scroll Endurance also includes a detachable palm rest to reduce drag on the desk surface.

Other cool features
In addition to its comfortable, ergonomic design, the Scroll Endurance also has adjustable sensitivity, which can be changed on-the-fly using the DPI button on the mouse. Another neat feature is the two thumb buttons, which perform back/forward browser navigation functions.
