The M75 is as fast as your reflexes, thanks to the 26000 DPI MARKSMAN sensor. It not just the sensor that's rapid, even the switches take your gaming up a notch. QUICKSTRIKE means there's no gap between the mouse buttons and the hyper-fast optical switches. So you get instant results every time you pull the trigger. It's also incredibly light - just 89 g, so you'll barely feel any resistance. And the ambidextrous design lets you swap the side buttons. So both righties and lefties can win. Good to know - Slipstream Wireless keeps the M75 connected without lag or a wire in sight - You're spoiled for macros and mapping - you can program 8 buttons with your most-used combos - Toggle the speed of your sensor by customising it in single DPI steps - A single charge will keep you gaming for up to 105 hours (with RGB off) - You've got RGB lighting of course, but Corsair's iCUE software really lets you tie the room together
