How to use it

- Try left, right and wheel clicks. Test side buttons if your mouse has them.
- Scroll in each direction, then use the double-click area below.
Before you start
Counts reflect browser events. Double-click recognition follows your device settings; this tool does not diagnose a faulty switch.
Common questions
Can this tell me whether my mouse has a faulty switch?
It shows the events your browser receives. Accidental repeated clicks may be visible, but this is not a definitive hardware test. Double-click recognition also depends on your device settings.
Do scroll counts represent wheel notches?
No. The counters show browser wheel events, which vary with your mouse, trackpad, browser and scrolling settings. Touchscreen taps are not counted as mouse-button tests.
