The Endgame Gear XM1R was the refined wired revision of the original XM1 at 70 grams with the PAW3370 sensor, widely regarded as having one of the best cables and click implementations in the entire gaming mouse market. The XM1R's flex cord was so smooth that many users forgot they were using a wired mouse, and the Kailh GM 8.0 switches set a standard for click crispness that wireless mice still struggle to match. The flat symmetrical shape with a subtle rear hump was specifically designed for aggressive claw grip. Endgame Gear's German engineering philosophy — precision over marketing — earned the XM1R a devoted following among enthusiasts who judge mice by feel rather than specs. It remains the reference point for what a claw-grip wired mouse should feel like.
