Logitech MX Master 4 vs Logitech MX Anywhere 3S
For working at a desk, get the MX Master 4. If you want one small mouse for a laptop bag, the MX Anywhere 3S costs less and goes anywhere.
Logitech MX Master 4
The best mouse for work: a sculpted shape that's comfortable all day, a fast metal scroll wheel plus a thumb wheel, very quiet clicks and about 70 days per charge.
Logitech MX Anywhere 3S
The MX Master's quiet clicks and fast metal wheel in a mouse small enough for any bag. Works on glass. Not shaped for all-day comfort.
