Mouse Tester
Test your mouse online: every button including the side ones, double-click check, scroll wheel and an approximate polling rate. Nothing to install.
Test every part of your mouse
Point inside the box, then press each button, scroll the wheel and move the mouse fast. Back and forward buttons are caught here, so the page will not navigate away.

Double-click check
A worn switch can turn one press into two. Two presses of the same button closer than 80 ms are flagged here: hardly anyone clicks that fast on purpose.
Polling rate (approximate)
Move the mouse quickly in circles inside the box. The browser counts how often it gets a new position. Treat it as an estimate: the browser and system can lower it, and 4000–8000 Hz mice usually read below their spec.
Common questions
How do I check my mouse for double clicking?
Click the left button inside the box at a normal pace for half a minute. Every press that arrives within a few dozen milliseconds of the previous one is counted as a suspected double click. If the counter grows while you click once at a time, the switch is wearing out.
How accurate is the polling rate test?
It is an approximation. The browser reports pointer movement it receives from the system, and Chrome and Edge pass more of it than other browsers. A 125, 500 or 1000 Hz mouse usually shows close to its setting; 4000 and 8000 Hz mice tend to read lower than the real rate.
Why do the side buttons not show up?
Some mice send the side buttons as keyboard shortcuts or macros set in the maker’s software. The browser then sees a key, not a mouse button. Reset those buttons to Back and Forward in the software and test again.
