Why AI Cannot Test Your Mouse
An AI chatbot has no way to reach the micro-switches inside your mouse, so it cannot tell you whether your left button is genuinely broken. Mouse button and wheel faults are hardware events your browser receives directly, which is why only a real mouse tester can confirm a diagnosis. If your cursor double-clicks on its own, or a button stops responding mid-game, a chatbot can only offer generic advice. This tool reads every button press, scroll tick, and movement event from your physical mouse, lights up the exact control that fired, and gives you a deterministic pass/fail answer plus an exportable report for a warranty claim.

How the Mouse Tester Works
- Keep your cursor over the test area and click each button at your normal pace. The matching part of the on-screen mouse lights up and the counter increments.
- Single-click for the chatter test — the tool times the interval between consecutive presses of the same button. An interval below your threshold is too fast for a human to produce on purpose and is flagged as switch chatter.
- Roll the wheel up and down to confirm both directions work, then move the mouse around to track distance and estimate the polling rate from movement events.
- Run the guided test to walk through every check in order, then read the diagnosis and export the report as proof for an RMA or support ticket.
Why does my cursor double-click when I only press once?
That is almost always a worn or dirty micro-switch, not a software problem. The switch contacts bounce and produce two signals for one press. Test with a normal single-click pace inside the area: repeated intervals below 40 ms between deliberate single clicks are a strong hardware signal, while fast intentional double-clicks sit well above that range.
How can I tell chatter apart from my own fast clicking?
People rarely double-click faster than about 60-80 ms between the two presses, and comfortable intentional double-clicks are usually 100-250 ms. If you are clicking once at a normal pace and still see very short intervals appear, that is chatter. Keep the threshold at the default 40 ms and single-click slowly to make the pattern obvious.
One of my side buttons never lights up. Is it broken?
Side (back/forward) buttons only register if your browser and mouse driver expose them as standard Button 4 and Button 5 events, which most gaming and office mice do. If a side button never lights up, first try it in another browser, then in your operating system's own mouse settings. If it works there but not here, the browser is filtering it; if it works nowhere, the switch or its connection is faulty.
Can I use this mouse tester for a warranty claim?
Yes. The guided test produces a report with per-button click counts, chatter hits, scroll results, movement distance, polling-rate estimate, and a pass/fail diagnosis. Download it as a TXT, CSV or JSON file and attach it to your support ticket. The CSV also logs every click interval, which makes quantitative evidence easy to inspect in a spreadsheet.
Why is my polling rate lower than the mouse box says?
Browsers often deliver pointer events at, or capped by, the monitor refresh rate, and some combine multiple hardware events into one JavaScript event. So a 1000 Hz mouse may read closer to 250 Hz here. This is a browser limitation, not a broken mouse. The estimate is still useful for spotting a mouse that drops to an unexpectedly low rate, which can feel laggy in games.
Does the test work with a laptop touchpad?
Yes for the basics. Touchpads expose left, right, and usually middle click, plus two-finger scrolling, so all three checks work. Side buttons and a meaningful chatter result really need a physical mouse. For the most reliable diagnosis, plug in a wired mouse.
