ERGONOMIC CENTERED DESIGN FOR PAIN-FREE PRODUCTIVITY – Say goodbye to shoulder, neck, arm and wrist strain. The RollerMouse Pro3 sits directly in front of your keyboard, keeping your hands within shoulder width and eliminating the need to reach, grip or move a mouse —ideal for users with carpal tunnel, tendonitis, or who want to prevent repetitive strain injuries (RSI).
If you can get it for below retail price it is a good value. Had an older version before with all of the same features. A must have tool if you use your computer for work many hours in the day.
I have used different models of this mouse over the years. All great and keeps me away from the surgeon.
Takes a few days to get used to but I’d never go back
