Unintended double-fire detector
This mouse double click test diagnoses hardware bounce. It is not a double click speed score and not a CPS Test. Compare the same mouse in a second browser before replacing it.
A mouse double click test is for the “I clicked once and the desktop opened the file twice” problem. Keep jitter clicking and CPS scores on the click-speed site.
Confirm each button on the mouse button test, then estimate travel with the mouse DPI test.
It watches how many click events arrive after you intend one press. A worn switch can fire twice close together. That is a device fault, not click speed.
No. Double click speed is a hand-speed task. This page diagnoses a mouse that double-fires on its own. Hand-speed tests belong on click-speed-test.net.
Two click events on the same button within 80 milliseconds are flagged. That window is a practical browser heuristic, not a manufacturer spec.
