Check whether the left, middle, or right mouse button reaches this page when you press it. This free mouse click test gives you a repeatable browser check with visible counts and no download.
Select one physical button, start the session, and press it once for each prompt. The page records the pointer input it receives so you can see whether the selected button responds consistently.
Start a session, then press the selected button once whenever the prompt is ready.
Ready for a 10-round mouse click test.
A good mouse button test keeps the setup simple. It checks one selected physical button at a time, separates valid presses from wrong-button input, and leaves you with counts that are easier to compare across computers or sessions.
Keep the default ten rounds for a quick check, or choose more rounds when a button fails only occasionally. Use the same number when comparing two sessions.
Choose left, middle, or right button. The page listens for the button you select, so you can test the exact control that feels unreliable.
Press Start test and wait for the first prompt. Setup clicks stay outside the reading because the test area begins listening only after the session starts.
Use the physical mouse button once, then wait. Do not use touch, Enter, Space, or another mouse button if you want a clean comparison.
Review valid presses, unexpected presses, and the fastest interval. Run the other buttons or another computer when the symptom is not consistent.
When you search for a mouse click test, you may want more than a button that changes color. This browser tool checks whether a selected physical mouse button sends pointer input to the page. It counts valid presses, notes presses from a different button, and measures the interval between valid presses. That makes it useful for a quick connection check, a new-mouse setup, or a comparison between computers.
This page is a button-response check, not a speed challenge. A CPS test asks you to click as quickly as possible, while a double click test looks for a rapid duplicate when you meant to click once. The mouse click test instead asks for deliberate single presses so you can verify the button you chose and compare its browser input with another button.
The control lets you focus on the button that is difficult to click, fails to open a menu, or behaves differently from the others. Test each button separately when you are checking a new mouse or investigating a hardware connection.
Use this for the most common pointer action: selecting, opening and dragging. Make one ordinary press per round and wait for the next prompt.
Use the wheel button when a new tab, paste action or other middle-click behavior is not reaching the browser. The page prevents the active context menu from interrupting the check.
Use this when the context menu does not appear reliably. The active test area suppresses the menu while running so the right-button event can be recorded.
The result combines the selected button, the requested rounds and the pointer events that reached the page. Look for a repeatable pattern instead of treating one session as proof about every program or operating-system setting.
Every requested round received the selected physical button and no other button was recorded inside the test area. If the button still fails elsewhere, compare the same mouse on another browser, application or computer.
The selected button completed the session, but another button was also pressed in the active area. Restart and keep your hand still between rounds so an accidental press does not muddy the comparison.
The page lost focus, received touch or keyboard input, or did not receive enough valid presses. Restart with the physical mouse connected and complete the requested rounds.
Testing is most useful when the conditions are repeatable. Put the mouse on a stable surface, choose the button that shows the symptom, and use the same single-press motion for every round. If you compare two computers, keep the selected button and round count unchanged before changing cables, drivers or settings.
Test the exact button that causes trouble instead of assuming all buttons match.
Keep your hand still after each press until the next prompt appears.
Repeat the same session when the result changes from run to run.
Compare another computer or known-good mouse before replacing hardware.
The tool observes pointer events that reach this browser page. It cannot inspect electrical contacts, the USB cable, wireless radio, operating-system drivers or an application's private input handling. A button can look responsive here and still fail in a game, design program or remote desktop session.
The result also depends on how the session is performed. An accidental press from another button, a touch gesture, a keyboard activation or a page losing focus can change the outcome. Treat the page as a fast diagnostic clue. For a repair or warranty decision, reproduce the symptom in the affected application and follow the device maker's support guidance.
The measurement in this tool runs in the browser. The page uses the visible test area, local event timing and result fields; it does not need your individual mouse presses sent to an API or stored in a user account. That keeps the test quick and avoids asking you to upload a file or install a diagnostic program.
The website can still load ordinary hosting, analytics or advertising services, and those services have their own data practices. Read the Privacy Policy for the site-wide explanation. The browser-only measurement promise applies to the click test itself and should remain aligned with the code as the tool changes.
Mouse input problems can look similar while requiring different checks. Use the result you need instead of combining speed, button response and duplicate-click signals into one score.
Check whether one physical click is being registered twice. That page focuses on suspicious duplicate events rather than general button response.

These answers cover the practical questions people ask when one mouse button feels inconsistent or does not behave the same way as the others.
It checks whether the selected physical left, middle or right button sends pointer input to this browser page. It reports valid presses, unexpected presses from another button and the fastest interval in the current session.
Choose a button, keep the default ten rounds or enter another number from 3 to 30, press Start test, and use that physical button once for every prompt. Repeat the session for the other buttons when needed.
Yes. Select one button at a time from the control. Separate sessions make it easier to compare which button responds, which button creates a context menu, and which button needs more investigation.
No. CPS measures how many intentional clicks you can make in a timed challenge. This tool asks for deliberate single presses to check button response, so its counts are not a speed score.
No. A double click test looks for a rapid duplicate event when you intend one click. Use this page for general left, middle or right button response, then use the Double Click Test when one press seems to open or select something twice.
The active area received a pointer event from a button other than the one you selected. Restart, choose the intended button again, and keep your hand still between prompts. A single accidental press does not prove a hardware failure.
You can open the page, but touch input is not a physical mouse-button test. For a meaningful result, connect the mouse you want to diagnose and use a desktop or laptop browser.
No. It means the selected button reached this page for the requested rounds under these conditions. Intermittent faults, application-specific problems, drivers and wireless issues may need another session or another computer.
