Mouse Test
Check mouse buttons, scroll directions and rapid double-click pairs with an adjustable threshold. Compare two tests and print a local report.
- Left
- 0 presses · 0 rapid pairs
- Middle
- 0 presses · 0 rapid pairs
- Right
- 0 presses · 0 rapid pairs
- Back
- 0 presses · 0 rapid pairs
- Forward
- 0 presses · 0 rapid pairs
- Wheel events
- ↑ 0 ↓ 0 ← 0 → 0
A rapid pair means two same-button presses within your threshold, not proof of switch failure. Intentional double clicks also count. Wheel counts are browser events, not physical notches. Back/forward buttons may be intercepted by your browser. No polling rate or hardware latency is measured; test data is never uploaded.
Check a used mouse or compare input before and after maintenance. Test results describe browser-observed events, not a diagnosis of a faulty switch.
Checking unexpected double clicks
Choose a threshold before testing and make deliberate single presses. Intentional double clicks also count as rapid pairs. Repeat the same pattern after a change and compare reports with the same threshold.
Scroll-wheel counters count browser events, not individual wheel notches. Operating-system gestures and browser back/forward actions may intercept input. Touch taps are excluded from button measurements.
Frequently asked questions
- Does a rapid pair prove the mouse is broken?
- No. The threshold is a timing rule, not a hardware diagnosis. Intentional double clicks and browser event timing can affect the count.
- Is test data stored on a server?
- No. Reports and event counts stay in this page session. Print a copy before navigating away.
- Can this measure USB polling rate?
- No. This tool tests buttons and browser scroll events; it does not measure hardware polling rate or latency.
