The stay-put base keeps your trackball-and your hand-in one place, helping to reduce wrist fatigue. Plus it saves desk space since you don’t need room to move around the device in order to move the cursor.
The larger size of the trackball makes it easier to control the cursor with less movement of your hand, delivering a great combination of long-lasting comfort and precision.
