Your hand will thank you, your desk will look clean, your productivity will spike.
Why Not Just Buy the Cheap One?
$15 mice have terrible sensors, squeaky wheels, and die within six months. The MX Master 3S has a MagSpeed wheel, quiet clicks, and lasts 70 days on a charge.
The Buy-Once Math
Replace a cheap mouse every year and you've spent $75 in five years with constant frustration. One MX Master for $100 works perfectly for five-plus years. Hands win.
