If you work long days at your computer or laptop, ergonomics is important. When you take ergonomics into account, you prevent RSI complaints or problems with your neck and back. An ergonomic mouse provides support for this. Ergonomic mouses relieve your hand, arm, and wrist because your hand rests on the mouse in a natural position. If you prefer to move your hand as little as possible, choose a mouse with a trackball. With this type of mouse, you only move your thumb to operate the cursor on your screen. Another additional advantage of a wired ergonomic mouse is that you'll never be without a battery. This way, you work undisturbed throughout the day.
