Corsair M75 Wireless Review: The Ambidextrous Mouse for Lefties, Priced Above Its Lighter Sibling
The M75 Wireless has swappable side buttons on both flanks, a 26,000 DPI sensor and long battery life. It is a rare true ambidextrous mouse, but at 89 grams and $129.99 list it needs a reason.
The verdict
The M75 Wireless is the ambidextrous mouse to get if you are left-handed or share a desk, because the shape is symmetrical and the side buttons can be raised or flattened on either flank. It weighs 89 grams, its main clicks have a long travel, and Corsair lists it at $129.99. If you are right-handed, the cheaper M75 Air is lighter and nearly as good.
Best forLeft-handed players and anyone sharing one mouse
What we liked
- Truly symmetrical shape with swappable side buttons on both flanks, so lefties are not an afterthought
- Corsair's Marksman optical sensor reaches 26,000 DPI and tracked accurately in reviews
- Long battery: about 105 hours over 2.4 GHz with RGB off, and up to 210 hours on Bluetooth
- PTFE feet glide well, and Slipstream wireless plus Bluetooth cover desk and laptop
What we did not
- At 89 grams it is far heavier than the 60 gram M75 Air, and a poor fit for twitch esports
- Main buttons have a longer travel than some rivals, which PCWorld noted
- Corsair lists it at $129.99, and the page showed it out of stock when we looked
- Unused side buttons need their caps flattened or removed to stop accidental presses
Left-handed gamers know the ritual. You find a mouse that looks right, check the photos, and see side buttons on one flank only. Most "ambidextrous" mice are symmetrical shells with a thumb rest for the right hand. The M75 Wireless is the exception, and that is the whole reason to talk about it.
Side buttons on both flanks
The M75 has buttons on its left and right sides. Corsair supplies swappable caps: raise the caps on the side you use, and flatten or remove them on the other so your grip does not trigger them. PCWorld, which gave it an Editors' Choice award, called it "the ultimate sharer's gaming mouse" for households where one player is left-handed and another is not.
GamesRadar's headline puts it as a must-see for a true ambidextrous design. How-To Geek's title is blunter: "Great for Lefties". Three outlets, one verdict.
The pairing matters more than it sounds. A mouse that suits both hands also suits two people, so a couple or siblings can share a desk with a quick cap swap, and a left-handed player can finally buy the same mouse as their right-handed teammates and get the same sensor, switches and battery.
What it weighs, and what that costs you
The catch is weight. The M75 Wireless is 89 grams, against 60 grams for the M75 Air, the lighter model in the same line. PCWorld listed that gap as its main weakness. It also noted that the main buttons have a longer travel distance than some rivals and judged the mouse better for casual FPS play than for competitive esports.
That matches how we would use it. At 89 grams you will not flick as quickly as with a 49 gram mouse like the Razer Viper V4 Pro, and a player chasing every millisecond should look at one. For a relaxed Valorant or Overwatch evening, or for work, 89 grams is fine.
