Endgame Gear OP1 8K Review
Weighing no more than 49 g, the ambidextrous OP1 8K promises exceptionally low latency, owing to its 8000 Hz polling rate and custom Kailh GX main button switches, which reduce actuation latency even further. PixArt's PAW3395 sensor is used, along with pure PTFE feet and a particularly flexible cable.
