Clickety clack, click, click. The sound of a mechanical keyboard isn’t exactly a hard one to recognise, and if you’ve ever been a fan of the floating key design, tactile feedback, and unmistakable ‘click’ that comes from playing games or typing up a review with a premium mechanical keyboard then you’d be hard pressed to find a more solid entry than Cooler Master’s Masterkeys Pro L RGB wired effort. Not only in terms of build quality and excellent use of industry-recognised Cherry MX switches, but also in its tasteful and over-the-top use of RGB lighting.

Look and Feel

At a glance, the Masterkeys Pro L is both elegant and quite subtle in its design, with the focus placed almost entirely on functionality over form. That is of course until you connect it via the high-quality, but somewhat short USB cable. Once that’s taken care of and the easy to use Cooler Master software is installed, the individual RGB key lighting fires up offering you a range of customisation options. Which range from subtle white light across the entire keyboard, or better yet the ability to create a profile that lights up a range of individual keys with the glowing colour of your choosing. Things get a silly from there, but we’d be lying if we didn’t say we had fun playing a version of Snake directly on the keyboard using the RGB lights. Or listen to some quality house music with the keyboard acting as a visualisation for the EQ.

The Masterkeys Pro L RGB hits a sweet spot of elegance, customisation, and down-right fun. Because when you can map a choice of 16.7 million colours to every key, there’s no reason why it shouldn’t be, well, fun.

Subtle, no-fuss, elegant, and solid. As per the specifications above you’ll note that in terms of weight this is one keyboard that won’t slide around any desk or flat surface. The build quality is exceptional and thanks to the onboard processor and response times, it’s the sort of kit that will make you feel like a pro when gaming. Ladder-stats in Quake Champions be damned! Ahem.

Type Cast

In fact, with the software and easy profile switching for RGB solutions that you can adjust on the fly for any application or game, it’s hard to fault the Masterkeys Pro L RGB. Our only issue with the whole package is that at 1.5 metres, the provided cable is a little short. On top of that though, maybe USB passthrough with additional charging would have been a nice touch. But, the Masterkeys Pro L is really focussed on one thing - delivering a world class mechanical keyboard. And even if you take away the RGB customisation it’s still excellent. With both look, feel, and overall build quality being exceptional.

A great entry from Cooler Master, and one that comes highly recommended.
