This tool checks that your mouse buttons and scroll wheel are working correctly. Move your cursor into the test area and click, scroll, and try each button — every click and scroll is counted and tracked live. It also measures your double-click speed by timing the gap between consecutive left clicks, useful for checking whether a mouse button is double-clicking unintentionally (a common sign of a worn-out microswitch) or registering clicks reliably.
This can indicate a worn-out microswitch inside the mouse button, a common failure mode in older mice, where a single physical click generates two electrical signals. If you see counts jumping by 2 on single clicks consistently, that's worth investigating on the mouse itself.
Most operating systems register a double-click when two clicks land within roughly 300–500 milliseconds of each other. This is mainly about your own clicking speed and OS settings rather than the mouse hardware itself.
