Lenovo R-Go Twister Ambidextrous Mouse

This vertical mouse is ambidextrous, i.e. suitable for both left- and right-handed users. Thanks to the patented switch & fold system, the Twister can be changed from a left-handed to a right-handed mouse and vice versa with one movement. By regularly alternating between your left and right hand, you distribute the load over both hands and prevent annoying complaints such as RSI. Moreover, the mouse is collapsible, so it is easy to take with you. So you can work ergonomically anywhere. The Twister mouse also helps you remember when it is time for a short break.
