Finalmouse claims its mouse has the absolute fastest click, quicker than the Logitech Superstrike and Razer Viper V4 Pro
"The fastest button input we've measured in a consumer electronic device."

According to niche mouse maker Finalmouse, its new hybrid mechanical-optical Starlight X mouse has faster clicks than any other it's tested, including the Logitech G Pro X2 Superstrike.
"At the centre of SLX is an entirely new TMR DS analogue click architecture.... The result is not simply the fastest click latency we've ever produced, SLX achieves the fastest click latency of any gaming mouse we've tested. And, beyond that, the fastest button input we've measured in a consumer electronic device."

Apparently, Finalmouse used to use its own XLat tester to measure the time it takes from the mouse switch electrically closing to the USB packet arriving at your system. But this isn't the whole story, because the time to actually press the button down, before the switch closes, is important, too. Decreasing this button-press time is the main benefit Logitech pointed everyone towards with the G Pro X2 Superstrike, and is what allowed the company to claim a 15–30 ms reduction in click latency.
Using copper tape on the surface of the mouse clicker in combination with its XLat tester and a machine it built to model a human click, Finalmouse has managed to measure the total time taken from starting to press the button to the data packet being received by the host system:
"[The pressing machine,] in combination with a little bit of copper tape and an XLat, will allow us to very accurately model the end-to-end latency of something that looks as closely as possible like a human click actuating a mouse."
Finalmouse compares a pre-production sample of the Starlight X to the Superstrike, the Razer Viper V4 Pro, and the Endgame Gear OP1 8K V2. The latter mouse is the fastest one that Finalmouse has measured just considering the latency from actuation to packet receipt. However, it lacks the pre-click latency reduction that analogue clicks provide.
Averaging 50 test clicks for each mouse, the two mice with analogue switches clicked significantly quicker than the two with traditional mechanical switches.
