The Switch mouse (successor to the Whale mouse) is an ergonomic and adjustable mouse that can reduce the risk of mouse related RSI injuries.
The size can be adjusted to fit hands from 17cm upto 21cm (size guide) to provide a perfect fit for any computer user, and the orientation can be swapped for right or left handed use via a V-shaped base, which puts the wrist and forearm into a comfortable and natural position.
Other features include a built-in palm support to prevent contact stress on the wrist, four-way scrolling dish to minimize repetitive motion, and programmable buttons for user-specified functions. A superb ergonomic mousing solution.
