Recommended for RSI syndrome (also known as tennis elbow), mouse arm and tendonitis, as well as when spending long hours at the computer (working, surfing or playing). This way all keys can be reached effortlessly and the desired ergonomic effect occurs: the hand is relieved from bending and additional effort, thus RSI syndrome can be prevented and the so-called mouse-hand or tennis-arm complaints can even be alleviated. The mouse is also ideal for medium-sized hands (for example, for travel and for the pocket). With the dpi button, the sensitivity of the mouse can be easily adjusted. In total, the mouse has 6 buttons, left-right click, scroll (click), dpi button and forward and backward button for navigating in the Internet browser. In addition, you can also turn it off completely at the on-off switch. The mouse has a quiet click and is equipped with a pleasant soft surface for optimal grip. It looks classy and elegant not only on the go but also at work. Recommended for use with Windows XP, Vista, 7, 8, 10 or later.
