Test your mouse buttons, scroll wheel, double click switch, drag function, and cursor tracking free in your browser. See every input light up live and catch early signs of a failing mouse before it costs you a game or a workday.
Click every button, spin the scroll wheel, try the drag handle, and move your cursor over the tracking box to get a full plain language summary of your mouse condition.
This test cannot measure exact DPI or true polling rate, since browsers only see processed cursor movement, not raw sensor data. Use our Polling Rate Test for a report rate estimate, or your mouse manufacturer software for exact DPI.
Press the left, right, and middle buttons, plus any side buttons your mouse has. Each region on the diagram lights up and counts clicks as it registers them.
Scroll up and down over the mouse diagram. The up and down counts should climb evenly with each notch of the wheel.
Click the left button once, deliberately, several times in a row. If the faulty double click counter rises without you clicking twice on purpose, your left switch may be wearing out.
Drag the handle to the drop target, then move your cursor over the tracking box to check for smooth, jitter free movement.
Confirms each button registers cleanly with no missed presses, delayed responses, or stuck states, whether it is left, right, middle, or a side button.
Flags clicks that register twice from a single physical press, the most common symptom of a worn left click micro switch.
Checks the scroll encoder in both directions and confirms drag operations track smoothly without skipping or losing the held object.
A browser only sees processed cursor movement after your operating system applies pointer settings, not the raw sensor data a mouse chip actually captures. This means DPI cannot be read directly from a web page, and true polling rate can only be estimated from event timing rather than measured at the hardware level. For exact DPI, check your mouse manufacturer software such as Logitech G Hub, Razer Synapse, or SteelSeries GG. For an estimated report rate, try our dedicated Polling Rate Test tool.
Mouse issues can sometimes look like controller or display problems. Check the rest of your setup with our other tools.

Click each button firmly and watch the diagram light up along with the click counter. A button that fails to register, responds late, or registers twice from one press is showing signs of wear.
This is usually caused by a worn or oxidized micro switch under the left button. Cleaning sometimes helps temporarily, but a consistent fault typically means the switch needs replacing.
No. Browsers only see cursor movement after your operating system processes it, not the raw DPI value from the sensor. Check your mouse manufacturer software for an exact DPI reading.
Yes. Button clicks, scrolling, and movement are detected the same way regardless of whether your mouse is wired, connected through a wireless receiver, or paired over Bluetooth.
Confirm your mouse software has the side buttons mapped to standard back and forward actions rather than a custom shortcut, since custom mapped buttons will not always trigger standard browser click events.
This points to a problem with one side of the rotary encoder inside the wheel, often from wear or dust, rather than a software or browser issue.
A dirty sensor lens, a glossy or uneven mousepad surface, or wireless interference are the most common causes. Try cleaning the sensor and switching to a plain fabric mousepad first.
Most trackpads support the same left click, right click, and scroll gestures, so basic button and scroll detection works, though drag and multi finger gestures may behave differently than a physical mouse.
Most gaming mouse switches are rated for tens of millions of clicks depending on the grade of micro switch used, though heavy daily use can wear them out sooner than the rated figure suggests.
