How to use

Position your hand so that the thumb rests comfortably in the thumb recess and move the mouse vertically to maintain a neutral wrist alignment. Use the scroll wheel and additional buttons as needed for navigation and shortcuts.

Recommendations

To reduce the risk of repetitive strain, adjust your workstation height and keyboard position so your forearm remains roughly parallel to the desk surface. Take regular short breaks and perform gentle wrist and shoulder stretches if you work for extended periods. If you experience persistent pain, consult a medical professional.
