## Detailed info

Mouse Test Lab is a free set of in-browser tools for checking a computer mouse. It is for PC gamers, people buying a used mouse, and anyone whose mouse has started double-clicking, skipping, or missing buttons. On the homepage you can test left, right, middle, and side buttons plus the scroll wheel, and it flags double-click bounce. Related tools measure clicks-per-second, polling rate up to 8000 Hz, real DPI, scroll-wheel skips, aim accuracy, and common click techniques. Nothing to install or sign up for, and results stay on your device. In Chrome and Edge the polling-rate test can read raw mouse events, so readings above 1000 Hz are possible; Firefox and Safari group events per frame and read lower.
