Ergonomic Mouse

Ergonomic mouse devices are designed with a specific purpose in mind: to enhance the comfort of the user while mousing and to help prevent serious injury from long-term daily computer use. 

A common problem that is reported after repeated use of standard input devices is hand and wrist pain, sometimes even running up the forearm. Regular mice are not designed for everyday use and therefore when they are used this often they trigger muscle tension and strain in the hands and wrists.
