The crew at MadShrimps say, if you are looking for a tunable FPS gaming mouse, the Corsair M65 RGB ELITE might be just what need.
While it feels about the same in hand as the previous M65 iteration, the fact that the Sniper and the thumb side buttons are brought closer together was a good design choice, since you can access these faster. CORSAIR has also made sure to optimize in order to make the chassis lighter, while the customizable weighting system has been retained.
