Ergonomic mice are designed with a specific purpose in mind: to enhance the comfort of the user while mousing and to prevent serious injury from long-term daily computer use. The first problem people usually complain about after repeated use of standard input devices is hand and wrist pain, sometimes even running up the forearm. Regular mice are not designed for use every day and therefore when they are used this often they trigger muscle tension and strain in the hands and wrists. If ignored these symptoms can turn into something serious like Carpal Tunnel Syndrome (CTS) or other repetitive stress injuries (RSI). The mice we offer below are made to combat this discomfort and keep your hand and arm in a neutral position, safe for regular use. Our best selling ergonomic mouse devices include the Evoluent Vertical Mouse, the Humanscale Switch Mouse, and the 3M Stick Mouse. Rest assured any model you choose from those shown below will provide the comfort and support you are looking for.
