Mouse Test
Test mouse buttons, double clicks, scroll wheel and pointer movement.
Click, double-click and scroll here
A single click that counts as two, or a button that only works sometimes, usually means a worn switch. Move the mouse quickly in circles to estimate its polling rate.

- 2 Double-click, then scroll up and down.

Frequently asked questions
What does movement events per second show?
It approximates how often the browser receives mouse updates, which is limited by the mouse’s polling rate and the screen refresh rate.
Why don’t back and forward buttons register?
Some mice need their software to send these buttons, and some browsers use them for navigation.
