The Penguin marks a major breakthrough in the battle to beat health problems created when computer users spend too much time handling a conventional mouse. It sets new standards of protection against a range of upper limb conditions such as repetitive strain injury (RSI) and carpal tunnel syndrome (CTS) by enabling right and left hands to share the workload and avoiding exaggerated movements of the wrist joint that can increase pressure on the soft tissues in the carpal tunnel. Regular switching of hands throughout the day helps prevent static muscle strain (SMS) in the arm and shoulder - a major source of discomfort in mouse work. The Penguin Mouse is also antimicrobial to inhibit the growth of bacteria - making it perfect for hot desking environments.
