Mouse test online. Buttons, wheel, and bounced clicks.
Click every button and scroll, and the test catches the fault most people search for: a worn switch that sends two clicks for one.
One check
- Mouse
Runs like the stress test: one check after another, with the progress along the top. Nothing you show the camera or say into the microphone leaves this page.
What it measures
Measured here, not assumed.
Every button
Left, right, middle, back and forward, each lit as it registers.
Bounced double clicks
Two presses of the same button within 80 ms, faster than a finger can go, are a switch bouncing.
Polling rate
Estimated from how often the browser receives movement, snapped to the common 125, 500 and 1000 Hz rates.
If it fails
The usual failures, and what fixes each.
- Single clicks become doubles
- The switch is worn. Replace the mouse, or the switch on a mouse worth keeping. Check the double-click speed setting is not set very slow first.
- A button never registers
- A failed switch or a damaged cable. On a wireless mouse, replace the battery and re-pair before assuming a fault.
- The wheel scrolls the wrong way or skips
- Dust in the wheel encoder. Clean around the wheel with compressed air.
Where a browser stops
What it cannot tell you.
- DPI and sensor accuracy, which a browser cannot read.
- Click latency end to end.
- Polling rates above 1000 Hz, which browsers coalesce.
Privacy
Nothing leaves this page.
The camera and microphone are read on this page and stopped as soon as they have been measured. The clip you can play back lives in the browser's memory and is discarded when you leave. The location check discards the position. The internet test sends random bytes to this site and nothing else. The result is stored nowhere unless you ask for it by email, and then only the fact that an email was sent is kept.
Questions
Mouse test, answered
- How do I test if my mouse is double clicking?
- Click the left button slowly and steadily in the test. Every click that arrives as two within 80 ms is counted as a bounce. Any bounces at all mean the switch is wearing.
- What polling rate should my mouse have?
- 125 Hz is standard and fine for desktop work; gaming mice run at 1000 Hz. The estimate here comes from movement events, so move the mouse steadily in circles for a reading.
- Does this work with a trackpad?
- Yes, for clicks and scrolling. Polling rate is not meaningful on a trackpad.
