This new 3-in-1 model of the iconic ergonomic Penguin Mouse combines Wired, Wireless and Bluetooth technology in one penguin.The Penguin 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.
