Drag and drop trial
Press, hold, move across this strip, then release.
No drag yet.
Timed session (optional)
Click normally for 30 or 60 seconds. Fewer than 20 clicks cannot support any conclusion.
No clicks yet.
Guidance only: a few events never prove a defect. Switches wear out gradually — retest on another computer to confirm.
Catch a faulty mouse button in one minute
- Click each button inside the test box and confirm its counter moves — left, right, middle, back and forward.
- Click the left button at your normal speed: pairs faster than the window count as double-clicks.
- Hold a button past 2.5 seconds to check the stuck-button warning, then release.
- Drag across the trial strip in one gesture to confirm hold-and-move still works.
- Optionally run a 30-second session and read the verdict — under 20 clicks it stays inconclusive by design.
- For scroll, DPI and polling-rate checks, use the Mouse Tester — this page is about click reliability.
Double-click questions
Why does my mouse double-click when I click once?
The micro-switch under the button wears out and bounces: one press sends two signals. Dust and old switches cause it; the counter above proves it before you replace anything.
What is the double-click window?
The maximum gap between two presses that counts as a double-click — 500 ms matches most systems. Shorten it to catch borderline bounces, lengthen it if you click slowly.
Why don't back and forward buttons respond?
Some mice lack side buttons, and some browsers reserve them for navigation. Click inside the box: if nothing lights up, your mouse likely has no such buttons.
Is a handful of phantom clicks proof of a defect?
No. A verdict needs a full session: at least 20 clicks with repeated phantoms. Retest on another computer — same behavior there points at the mouse, not the system.
