Your wrist will thank you, and the scroll wheel is pure magic.
Why Not Just Buy the Cheap One?
Budget mice ($15) develop double-click issues, noisy scroll wheels, and cramp your hand. The MX Master 3S has a silent, magnetic scroll, ergonomic shape, and runs months on a charge.
The Buy-Once Math
A cheap mouse lasts six months then you buy another. Over 5 years that's $150 for junk. This mouse lasts 5+ years and boosts your productivity. The cost per day is pennies.
