Ambidextrous mice face an uphill battle; they’ve got to serve two masters at once with very different needs. The M55 RGB Pro may just pull it off, though. While Corsair’s latest isn’t the best gaming mouse you can get your hands on, it offers good value at a low cost nonetheless ($39.99 / £44.99, to be precise). Chic and user-friendly in spite of a few design hiccups, it’s arguably better than most alternatives vying for your cash.
Even though Corsair had a go at asymmetric mice with the Katar back in 2015, this is an aesthetic u-turn - and a welcome one at that. Rather than bulky grey plastic and sports-car grills, the M55 opts for a tear-drop shape that’s both sleek and understated.
Besides the standard RGB light-show, it also provides four programmable buttons (two on each side), a singular DPI button on the top, and a rough, grippy surface that improves control. It's sleek and understated, but well designed to be user friendly.
Weighing in at just 86g, the M55 backs up that speed with a middle-of-the-road 12,400 DPI sensor. However, the real headline is asymmetric control (obviously). Corsair handles this balancing act with ease; swapping from left to right-handed grips is as easy as holding down the two programmable buttons. Once you’ve done this, those extra buttons on the other side will be disabled to make sure you don’t hit them by accident.
Even though it’ll feel weird at first if you’re not used to asymmetric mice, the M55 RGB Pro is comfortable for both left and right-handed users. The case’s texture also makes it feel very secure underhand. In fact, the only design choice I wasn’t a big fan of would be the rubber side grips. While these do the job, they also give the impression of cheap plastic.
Unfortunately, things aren’t so rosy when it comes to performance. I wasn’t mad-keen on the M55’s click action, and those Omron switches are a little more resistant than I’m happy with (a colleague called them “spongey”). The scroll wheel was hard to reach with my fingertip grip, too.
Still, it’s not all bad. The M55 boasts a fantastically smooth glide, and I appreciated the chance to program each individual DPI profile. What’s more, it doesn’t cost much - $50 / £45. This isn’t the fastest mouse on the market by any means, but you can’t really complain at that price.
Because there aren’t many ambidextrous pointers to speak of, I’m more willing to overlook the M55 RGB Pro’s flaws. And realistically? These aren’t issues that’ll ruin your enjoyment all that much. Corsair’s latest mouse isn’t going to blow your socks off by any means, but it’ll serve you well even so.
