Mouse Test
Buttons and wheel
Point at the mouse below, then press every button and roll the wheel. The page won't scroll, open a menu or go back while you test here.
| Button | Presses | Shortest gap | Double-click faults |
|---|---|---|---|
| Left | 0 | – | 0 |
| Middle (wheel) | 0 | – | 0 |
| Right | 0 | – | 0 |
| Back (side) | 0 | – | 0 |
| Forward (side) | 0 | – | 0 |
A press this soon after letting go of the same button is counted as a fault: people can't release and press again that fast, but a worn switch bouncing can.
Click speed test (CPS)
Choose a time, then click the box as fast as you can. The timer starts with your first click.

How often the mouse reports its position. Chrome and Edge show the real rate; Firefox and Safari can cap it at your screen's refresh rate. Wireless mice may drop to a lower rate to save battery.
Test every mouse button and the scroll wheel, catch double-click faults, measure your clicks per second (CPS) and your mouse's polling rate - in the browser.
Check a new or second-hand mouse in a minute: press every button - left, right, middle and the two side buttons - and roll and tilt the wheel to see that each one registers. The test catches the classic worn-switch fault where one click arrives as a double click, and shows the shortest gap for each button so you can judge for yourself. Then measure your click speed in clicks per second, and your mouse's polling rate. Nothing is installed and nothing leaves your browser.
