A mouse test — or mouse button tester, if that's what brought you here — checks whether every button, the scroll wheel, and the sensor on your mouse are actually doing what they're supposed to. The most common failure point is the microswitch behind the left-click button — after a year or two of regular use it tends to wear down and start firing two click signals from a single press, a problem known as double-click chatter. Running a quick test here takes under a minute and tells you exactly which part is failing before you decide whether to fix it or replace the mouse.
What This Tool Checks
- Left, right, and middle click — the three buttons every mouse has.
- Back and forward buttons — the side buttons on most gaming and productivity mice.
- Double-click chatter — flags any two presses on the same button that land less than 60ms apart, a telltale sign of a worn microswitch.
Testing Your Scroll Wheel
Scroll wheel problems are easy to miss because they only show up as an annoyance — the page jumping two lines instead of one, or refusing to scroll at all in one direction. The counters above track scroll-up, scroll-down, and left/right tilt-scroll separately, so a wheel that only fails going one direction (a common symptom of a worn encoder) is obvious instead of something you just get used to.
How to Read the Results
Each button starts greyed out with a "Not tested" label. Click it once and it switches to a green checkmark, confirming your browser received that click event. If a button flashes an amber warning icon instead, the tool detected two down-events in rapid succession from a single press — that's the chatter pattern associated with double-click issues, not a bug in the test itself.
Diagnosing a Specific Problem?
If you clicked here expecting exact clicks-per-second numbers, use the Click Speed Test instead. For gaming performance and Hz measurements, try the Polling Rate Test.
Frequently Asked Questions
How do I test if my mouse buttons work?
Click inside the test box with each button. Each one lights up the moment it registers, so a dead or unresponsive button is obvious immediately.
What is mouse double-click chatter?
It's when a worn microswitch fires two click signals from one physical press, usually 10-50ms apart. This tool flags any gap under 60ms as likely chatter.
Does this work for wireless mice?
Yes — wired, Bluetooth, and 2.4GHz wireless mice all report the same standard browser events, so the test works identically across all of them.
Is it free and does it store my data?
It's completely free and runs locally in your browser — nothing you click is recorded, uploaded, or stored anywhere.
Do I need to download a mouse click test program?
No. Unlike desktop click-test programs, this tool runs entirely inside your browser tab — there's nothing to install, and nothing left behind when you close the tab.
