# Bloody Gaming (A4Tech Company)

> Bloody Gaming is the gaming arm of A4Tech, the Taiwanese peripheral maker that has been building mice since 1987. Launched in 2011, Bloody stakes its identity on Light Strike (LK) optical switches - key and click mechanisms that fire on a broken beam of infrared light rather than metal contact, which the company clocks at a 0.2ms response. Sold mostly in the $25-$60 range through Amazon, its own store, and retail, Bloody targets value-focused PC gamers with mice, keyboards, and headsets - run in North America from Chino Hills, California.
