The SteelSeries Prime was a clean competitive mouse at 69 grams wired with the TrueMove Pro sensor, designed with direct input from over 100 professional esports players. The Prime introduced Prestige OM optical magnetic switches that used magnetic actuation for zero debounce delay and a lifespan rated at 100 million clicks. Its shape was the result of extensive pro-player testing, creating a comfortable ergonomic contour purpose-built for competitive use. The Prime represented SteelSeries' attempt to re-enter the competitive mouse conversation after the ultralight revolution had shifted attention to brands like Finalmouse and Logitech. At 69 grams wired, it was SteelSeries' lightest ergonomic mouse at the time of release. The Prime signaled that SteelSeries was serious about weight-competitive esports mice.
