Finalmouse claims its mouse has the absolute fastest click, quicker than the Logitech Superstrike and Razer Viper V4 Pro

Finalmouse, a niche mouse manufacturer, claims its new Starlight X gaming mouse features the fastest click latency of any device tested, including Logitech’s G Pro X2 Superstrike. The company attributes this to a proprietary TMR DS analogue click architecture, which it states reduces latency to 2.0 milliseconds—faster than any other gaming mouse or consumer electronic device measured by Finalmouse.

The Starlight X’s performance was evaluated using Finalmouse’s XLat tester and a custom machine designed to simulate human button presses. Unlike previous tests that measured only electrical switch closure, Finalmouse now tracks total latency from the start of a button press to data packet receipt. This end-to-end approach includes both mechanical actuation and signal transmission.

In comparative tests against the Superstrike, Razer Viper V4 Pro, and Endgame Gear OP1 8K V2, the Starlight X averaged 50 clicks per mouse. Analogue switches, including those in the Starlight X, consistently outperformed traditional mechanical switches by roughly 3–5 milliseconds under normal finger-press conditions.

While the Starlight X’s 2.0 ms latency is theoretically impressive, practical benefits may be limited for most users. Human reaction times average around 165 ms, and even professional gamers rarely exceed 100 ms. Additionally, pre-production samples suggest long shipping delays, with some reports indicating waits measured in months rather than days.
