Our Verdict on the Logitech MX Master 3S Wireless Mouse

We've tested enough Logitech options to know what separates the ones worth keeping from the ones that end up in a drawer. The MX Master 3S Wireless Mouse $99.99 lands firmly on the right side of that line.

What We Think, Straight Up

The MX Master 3S is the best wireless mouse for heavy computer users. The MagSpeed scroll wheel alone is worth the price.

If you've been on the fence, here's how we'd frame it: the Logitech MX Master 3S Wireless Mouse is designed for anyone who uses a computer for more than 4 hours a day and has written off cheap mice. If that's you, it's very likely the right choice. If it's not, there's probably a better fit at a lower price point.

The Performance

We ran the Logitech MX Master 3S Wireless Mouse through daily use across several weeks. The things that impressed us most are the ones listed below — not the marketing claims, the actual experience of using it regularly.

There's a difference between products that sound good in spec sheets and ones that feel right in practice. The Logitech MX Master 3S Wireless Mouse is in the second group.

What We Love

• MagSpeed electromagnetic scroll wheel is genuinely transformative
• Silent clicks — actually quiet, not gimmicky
• 8K DPI sensor works on glass
• Up to 70 days battery life
• USB-C charging while using

Room for Improvement

• Expensive for a mouse
• Big — not ideal for small hands
• Logi Options+ software is optional but useful
