Penguin Vertical Mouse The Penguin helps reduce repetitive strain injury (RSI) and carpal tunnel syndrome (CTS) by enabling right and left hands to share the workload. Helps prevent static muscle strain (SMS) in the arm and shoulder. Naturally comfortable, the vertical alignment encourages a more ergonomic operating position.
Ambidextrous design has a central "bow-tie" switch allows for easy transition between right and left handed use. Easy-glide symmetrical base allows the user to rest either hand comfortably alongside the vertical structure, encouraging the use of the bigger muscles in the fore and upper arm to maneuver the mouse. Fine cursor control is still achievable with small hand and/or finger movements. Precision performance laser for accurate tracking.
