Corsair M55 RGB Pro Mouse Review

Having spent the last week using Corsair's new ambidextrous M55 RGB Pro mouse, I think it is safe to say there is room for improvement.

Starting with the good, though, Corsair has gone with a pretty safe shape – it is what I would call ‘Sensei-inspired', being generally similar to the classic Sensei shape, but with a few differences here and there. That means it's comfortable to use with a variety of grip styles, while the mouse as a whole feels generally pretty solid in the hand despite its 86g weight.

On top of that, we have a good, albeit straightforward RGB implementation, while Corsair's iCUE software offers a range of control over profile, DPI stages, macros and more.

Unfortunately, I did run into a few problems with the mouse and its design. First of all, the primary buttons exhibit a fair amount of post-travel, giving the clicks a mushy feel, while the braided cable is also quite stiff. On top of that, while the PixArt PAW3327 sensor is great in terms of its tracking and general use, the lift off distance is very high – my sample would still track when placed on top of three DVDs.

Those issues, when looking at the mouse as a whole, aren't major enough to be absolute deal-breakers (though the LOD is the most significant problem for me), but I think they do really hold the mouse back when we look at the wider market. What I mean is this: I fully understand Corsair's approach here – they don't have an ambidextrous mouse in their product portfolio, and it's a market segment they want to target.

That said, the M55 RGB Pro is offering nothing new outside of Corsair's product stack – we've seen similar ambidextrous mice on the market for years from the likes of SteelSeries, Zowie, Logitech and so on. So when you consider that the M55 RGB Pro has an MSRP of £44.99, things become very difficult for it. To give you three examples of similar, ambidextrous mice you can get at the same price or less – there's the SteelSeries Sensei 310, Dream Machines DM1 FPS and Logitech G305.

A couple of years ago, I think this mouse would've scored 8/10 and earned a solid recommendation. However, the industry has really upped its game and there are now a lot of top-quality mice available at this price. In my opinion, each of those three mice listed above have better sensors than the M55, better primary buttons and better cables. Heck, the G305 is even wireless and costs £11 less than the M55.

So while the Corsair M55 RGB Pro may not be a bad mouse overall – it can certainly be improved, yes, but it's not terrible – we have to look at its place in the market as a whole. £45 might be relatively affordable in regards to Corsair's product stack, but you can get a number of higher-quality mice for the same money or less, by going elsewhere.

If you do want to buy the Corsair M55 RGB Pro, Overclockers UK has it in stock for £44.99 HERE.

Pros

• Comfortable shape.
• True ambidextrous design, with side buttons on both sides.
• iCUE offers control over all the key areas.
• Feels solid yet weighs just 86g.

Cons

• Very high lift off distance.
• Primary buttons have noticeable post-travel.
• Braided cable is stiff.
• Looks pricey for what you gets versus the competition.

KitGuru says: Priced at £30, as an ambidextrous sibling to the entry-level Corsair Harpoon, I think the M55 RGB Pro would do well. At £45, however, there are all-round higher quality options available.
