Double Click Test
Check whether a mouse button is sending suspicious rapid repeat events while you make deliberate single clicks. ReactionMetric guides the pace, locks to one button, logs browser timing and produces a copyable evidence summary.
One button at a time
Interval evidence
Runs locallyMake slow single clicks
Press Start test, then click once only when the panel says READY FOR ONE CLICK. The guided pause reduces false positives from intentionally fast clicking.
Click timing log
Only browser-received mouse events are shown. A suspicious event means a same-button repeat landed inside your selected threshold during the guided single-click window.

Evidence of accidental repeat events
A worn or noisy switch can sometimes make one intended press appear to software as multiple very closely spaced events. This page measures what reaches the browser and highlights unusually rapid same-button repeats during a guided single-click test.
Repeated suspicious events across multiple runs are stronger evidence than one isolated interval.
Not a hardware oscilloscope
A web page cannot see the physical switch contacts or prove why an event happened. Firmware debounce, operating-system processing, browser behavior, macros and your own clicking style can all affect what arrives here.
Before repair, replacement or warranty action, reproduce the issue in a second run and, when practical, another USB port, browser or computer.
Why guided single clicks are better than a speed game
Mouse double click test FAQ
How do I test if my mouse is double clicking by itself?
Select or auto-detect one mouse button, start the guided test, and make deliberate single clicks only when prompted. If extra same-button events repeatedly arrive inside the suspicious-repeat window, rerun the test and confirm the pattern.
What threshold should I use?
There is no universal browser-level threshold that proves a hardware fault. ReactionMetric defaults to 80 ms because it is short enough to surface unusually rapid repeats during deliberate single-click testing, and it lets you tighten the window to 30 or 50 ms. Treat the result as evidence, not a hardware diagnosis.
Can I test right click or middle click?
Yes. Left, right, middle, back and forward buttons are available where the browser exposes them. Side-button behavior varies by browser and operating system.
Why not just count the browser dblclick event?
The browser can emit dblclick after two intentional clicks as well as after an unwanted repeat. ReactionMetric records that signal, but the guided same-button timing window is the primary diagnostic evidence.
Is this a double-click speed test?
No. This page is optimized for accidental repeat diagnosis. If your goal is repeated clicking speed rather than switch behavior, use the CPS Test.
