How to run this check
Click slowly and deliberately inside the pad. Test each button and scroll in both directions.
Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
A short click interval can be intentional; browser timing cannot prove switch bounce.
If something seems wrong
Compare deliberate single clicks in another app and USB port before suspecting a worn switch.

No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
