The majority of gaming mice are ergonomically tailored for right-handed gamers, leaving left-handed users to look for the rare exception, or an ambidextrous rodent. Cooler Master's new CM310 falls into the latter category, though there's a caveat.

Cooler Master's "ambidextrous" billing refers to the CM310's symmetric shape, which the company claims makes it an effective rodent "whether you're normal or southpaw." It's also "specially engineered" for both palm and claw grip styles (Cooler Master doesn't say which of those it considers "normal").
