[USED] Logitech MX Master 3 Wireless Mouse 4K DPI

See the actual unit before you buy

Not a stock photo and not a different mouse — this is the exact unit you will receive, filmed on 22 September 2026. The clip runs over the top shell, the MagSpeed wheel, the thumb wheel and side buttons, and the underside with its model label and serial, so you can judge the condition yourself.

The mouse that came in the box with your machine is the reason your wrist aches by the afternoon. The Logitech MX Master 3 is the one most people switch to and never switch back from — a full-size, right-handed shape built to be held for eight hours rather than five minutes.

The scroll wheel is the reason to buy it

MagSpeed electromagnetic scrolling ratchets click-by-click for precise work, then spins freely when you flick it — roughly a thousand lines in one second. On a long spreadsheet, a timeline or a codebase, that is the difference between scrolling and arriving.

Quiet enough for a shared room

The clicks are around 90% quieter than a standard mouse. If you work next to someone, record audio at your desk, or use a laptop in bed, you will notice this on day one.

4000 DPI, and it tracks on glass

The Darkfield sensor works on a glass tabletop where ordinary optical mice give up, so no mousepad is required. Accurate enough for design and photo work, not just moving windows around.

Three machines, one mouse

Pair it with up to three computers — Mac, Windows or Linux — and switch with a button underneath. Logi Options+ adds app-specific button profiles, so the thumb wheel can mean one thing in Photoshop and another in Excel.

Seventy days between charges

A full charge lasts up to 70 days, and one minute on USB-C buys three hours — you plug it in while you make coffee, not overnight.

This is the exact mouse filmed for the review above — a used unit, inspected and tested before listing, which is why it is a fraction of the price of a new one. Plug in the receiver and your hand will thank you by the end of the week.
