Valorant Reaction Time Test | Train the Millisecond That Wins Duels

Most Valorant duels are decided in under 200 ms. SERO measures the exact peek-and-click window — the gap between seeing an enemy and committing to a shot.

Why Reaction Time Decides Most Valorant 1v1s

Time-to-kill in Valorant on body shots is short and the side who fires first usually wins. Trimming 20–30 ms off your stimulus-to-click window translates directly into peeker advantage.

How to Train Without Booting the Game

Use SERO between matches in the same browser tab. 90 seconds, no install, no launcher, no GPU. Stay sharp without alt-tabbing into a heavy aim trainer.

FAQ

Will this make me Radiant?

No tool can. But Radiant-level reaction floors sit around 150 ms — SERO shows you exactly how far you are from that.

Is it allowed alongside Valorant?

Yes. It is a separate browser page; not a Valorant overlay, plugin or memory reader.

How often should I train?

Daily 90-second sessions outperform long once-weekly sessions for reaction-floor improvement.
