Corsair IRONCLAW RGB FPS/MOBA Gaming Mouse Review

A Closer Look and Performance

The IRONCLAW comes hard-wired with a very nice quality black-braided cable. It also features the newly designed USB header, which is a little sleeker and more durable than their previous design.

Bigger Is Better

The IRONCLAW is a great looking mouse, and unmistakably a Corsair mouse in regards to the design. It’s got plenty of unique style points though, setting it well apart from their other ranges like, even if it does have a similar front end grille design like the Sabre, and Glaive for example.

The left side buttons are oversized, with easy to use switches. The switches pop out of the side quite a bit, but they’re still set back from the bottom edge of the mouse, as the whole thing curves in quite a lot. There’s an even deeper cut-away where the tip of your thumb would rest, and loads of hard-texture grip on the left. Overall, this promotes a really comfortable grip with easy and natural use of the side buttons.

Right Handed Only

The IRONCLAW is right-hand use only, due to the ergonomics of it, and only having left side buttons. The mouse is quite wide, but not so much to be unwieldy. There’s a slight inward curve on the right side, as well as more of that hard-wearing grip. The combination of both grips and the shape of the mouse makes it quite easy to lift the mouse up. Plus, since it only weighs 105g, it’s pretty easy to shuffle around in general anyway. What’s most surprising is that despite the lightweight design, it still feels planted, robust, and study.

As you can see, the mouse sweeps up quite quickly from the back into a large top hump. The shape of the mouse then takes a slow and long curve down to the front. Overall, the longer and curvy design means the whole mouse can fit in the palm of your hand, and provide you with good finger ergonomics for those long gaming sessions. It’s the first mouse in a long time that fits my hand better than my Roccat mouse; I’ve had my current desktop mouse for three years, so that’s saying something given how many I review.

Great Ergonomics

Keeping with that ergonomic theme, the mouse slopes off slightly to the right. This means you’re not fully twisting your wrist parallel to the desktop. It’s a tiny tweak, but one that can greatly improve comfort. Furthermore, just like the oversized buttons on the left side, the mouse wheel and DPI toggle buttons are pretty sizable too. Albeit, they still feel light, nimble and responsive, they just look a wee bit chunky.

The base of the mouse is designed to glide with ease, thanks to a fairly smooth base, and four huge slipmats that provide an excellent amount of glide. We tried it on the wooden desk, hard cloth, and even an aluminium gaming surface, and it felt right at home on them all.

Corsair prides themselves on quality, and there’s certainly plenty to praise about the IRONCLAW. It’s not their most complex or outlandish looking gaming mouse ever. However, it doesn’t need to be. It’s just a quality product, made slightly bigger for the benefit of those with larger hands/fingers. It’s a finely tuned tool that favours performance over all else. That being said, I’d actually go as far to say that it’s an OK looking mouse, but it’s not particularly pretty either.

Great Customisation

What this mouse lacks in looks though, it makes up for with brilliant performance. For starters, the OMRON switches are every bit as responsive and fast acting as you could hope for. The fully programmable design means you can reconfigure the mouse buttons with macros, shortcuts, and much more to suit your needs. Of course, you’ll need the iCUE software, which is handy for tweaking the RGB too. However, you can save all the settings directly to the mouse and don’t always need the software loaded/installed unless you want to make further changes.

The RGB is looking pretty sharp too, with a two-zone effect that lights up both the inner section of the scroll wheel as well as the Corsair logo on the rear of the mouse. For RGB, it’s pretty understated for Corsair, but that’s fine with me.

18k Optical Brilliance

The upgraded sensor of the IRONCLAW is staggeringly brilliant too. It’s the same sensor Corsair are rolling out in a few new mice at the moment, as well as upgrading some older models for their 2019 reissues. It tracks with exceptional precision, and with 1 DPI increments, you’ll have no issues dialling in exactly the level that’s right for you. It’s one of the slickest optical sensors I’ve ever used, and with surface calibration and other processing tools on hand, you can ensure it’s always working its best.
