This mouse tester checks every part of your mouse in one place: left, right, and middle clicks, back and forward buttons, the scroll wheel, double-click timing, drag response, cursor position, and total distance traveled.
Whether you just unboxed a new mouse or you suspect an old one is starting to fail, running through every section here takes less than two minutes and tells you exactly what’s working and what isn’t.
The button panel highlights left, middle, right, back, and forward clicks the instant you press them, so you can confirm all five (if your mouse has that many) are registering correctly. The scroll section counts every tick in both directions, the movement trail visualizes your cursor path, and the position counter shows real-time X and Y coordinates alongside total distance traveled.
The double-click test measures the exact time in milliseconds between your two clicks. Operating systems use a maximum double-click interval — clicks closer together than that register as a double-click, clicks further apart register as two separate clicks. This section lets you see your own timing and confirm your mouse is registering double-clicks consistently rather than randomly.
One of the most common mouse failures is a worn-out switch that fires two signals from a single physical click — often called a ghost click or an unintentional double-click. If you click once on this tester and the counter jumps by two, or your double-click test shows an impossibly short interval you didn’t actually perform, that’s a strong sign your mouse’s switch is wearing out, and it’s worth checking against your results on our Mouse Click Counter.
The scroll wheel section confirms your wheel registers both up and down ticks cleanly, without skipping or double-counting — a common failure point on older mice. The drag test checks whether your mouse maintains a consistent click-and-hold while moving, which matters for anything from dragging files to selecting text to in-game actions that rely on click-and-drag input.
