On Friday evening, I arrived home at about 6.30pm. I had my girlfriend in tow, having picked her up from work for a lovely weekend together. We donโt see each other often, as she lives an hour away. Waiting for me on my desk was a brown, cardboard box, with CoolerMaster tape all over it. โCool,โ I thought, โIโll have a very quick look at this keyboard Iโve been sent for review, and then Iโll spend the most-part of the evening watching bad TVโ.
How very wrong I was. After plugging the CM Masterkeys Pro L into my PC, I went into a state of awe. Colour flashed before my eyes as I touched the keys, reading the manual frantically to find out how to change profile and make ever more pretty things happen. I only realised that Iโd been playing around with it for hours when mโlady wandered through and gave me THE LOOK. The look that says โyouโve been on there for ages and weโre supposed to be spending time together, you pratโ.
I replied simply; โBut you can play Snake on it!โ
Who What When Where Why?
Coolermaster are well-known for their high-quality gaming products, and at present they seem to have two comparable seriesโ of high-end keyboards, both costing around ยฃ100-ยฃ130 at the top end; The CM Storm MECH family, and the Masterkeys Family. Their CM Storm range is their โpro-gamerโ focused side, with a focus on macro-keys and portability, whilst their Masterkeys range is focused on style and all-around everyday usage, and itโs this family which Iโll be talking about today.
The Masterkeys boards come in two types; L and S, with the only difference being that the L model has a num-pad, whilst the S model doesnโt. Both versions are available with Red, Blue or Brown Cherry switches; it just so happens I have brown.
The whole idea behind this family of keyboards seems to be a mix between a designated gaming keyboard and an all-purpose everyday device, with extensive macro key-overwriting and completely customisable LED backlighting.

Not bad stats by any means, and there are only two features which I feel are missing from the keyboard. Until this arrived, I was using a Corsair Vengeance K90, which allows you to change volume simply by spinning a roller on the top right of the peripheral, allowing easy control of volume at a momentโs notice. Whilst itโs only a minor complaint, in comparison, having to hold โFN + Page Up/Page Downโ on the CM Masterkeys to control volume is a bit of a chore. The absence of USB pass-throughs is also a little disappointing, but again, itโs only a minor complaint. Overall the feature list is very impressive, with a variety of customisation options to suit and enough power under the hood to successfully support them without compromising the response rate.
It looks good on paper, despite the braided cable being a little short for certain configurations, but you can never be sure until youโve been hands-onโฆ
Look at me! Look at me! โ Appearance and build quality.
When turned off, I wonโt lie, it isnโt the most impressive looking little chappie. Plain, matt black with white paint behind the keys and a pretty standard layout, without a good hard look it would be easy to mistake this for any other generic keyboard. The only real tells are the high-quality braided cable, the FN (function) button; commonly only seen on laptops; the CM logo replacing the Windows key and the strangely labelled buttons on the top row.
On the bottom of the keyboard youโll find customary flip-out angle supports and an interesting setup of grooves, designed to allow flexibility and choice in terms of cable protrusion. Itโs a really nice idea, which somewhat circumvents some of the issues I had with the cable length, and that I personally havenโt encountered before, though I know itโs been in use for a number of years. The cable also separates from the keyboard entirely, as itโs simply a micro-USB connector, (Think โphone charger wire,โ) so if you were pushed for length you could theoretically find a longer equivalent wire to plug in. This also could come in useful for wandering gamers; those who frequent LAN parties and the like.
The whole thing has a really nice, heavy feel, which reassures that itโs a well-made product which isnโt going to smash if I drop it. It exudes class and professionalism whilst turning its back on the in-your-face look of many gaming keyboards. Whilst as a teenager I would have appreciated and preferred the over-stated look of other gaming keyboards and mice, I feel that this fits the person Iโve become now Iโve begun my actual career, and that it would also be a good fit for other young professionals (like myself) who also enjoy their games a bit more than they should!
You can call me โMr Fancy-Pantsโ.
โฆBut that doesnโt mean you should underestimate how flashy the CM Masterkeys CAN be. Yes, on the outside it looks professional and basic, but once you turn it on you understand the real power behind it. The keyboard comes with a variety of cycling lighting modes which are fully customisable through either the keyboard itself or the downloadable software. I honestly preferred to use the program to customise using the software, which also automatically downloads and installs new firmware to your device quickly and easily.
At current, available modes include Static (a single colour for the entire board,) a variety of typing-activated modes (Ripple, Cross Mode, Single Key,) Colour Wave (which cycles the colours through the RGB spectrum across the entire board and looks GORGEOUS,) System status (which shows either a sound equaliser or CPU use,) Snake (?????), and Customise, which is arguably the most useful. All modes run smooth as butter, and switch instantly through the โFN-F4โ combo. Most can be completely customised, with both active and background colours available for modification. My favourites are easily Colour Wave, Ripple (with random colours,) and the equaliser system status setting, which is actually active whilst I type this and listen to the latest Podquisition. All three are incredibly flashy and colourful, bringing life and excitement to any typing task; though for gaming they can be a little distracting.
Whilst gaming, I found myself primarily using the Customise function, which, after setting up correctly, improved my gaming quality of life considerably. In short, you can set each and every key to have its own individual brightness and colour, which led me to colour- code keys based on keybinds for the game Iโm currently playing.
Here you can see my current customisation for The Witcher 3: Wild Hunt. As you can see, Iโve coloured my most commonly used keys red; so that I can easily find my bearings in the dark. Iโve coloured other commonly used keys yellow, again, as an impromptu reminder. Commonly used menu keys and quicksave are coloured various purples and my quick-use items are coloured green. I found myself constantly forgetting the shortcut for rest, so I coloured N orange. Iโm sure you can see the pattern! For the number keys, I chose to colour them based on the sign they stand for, which has led to me switching between them more effectively without the risk of forgetting which key stands for which power. Finally, I gave the lighting mode toggle, the function key and the volume control keys a light glow too, so that when gaming late at night I can switch to different lighting modes or change volume easily without having to pause, get up and turn the light on.
This is the kind of complete lighting customisation I was looking for. When Iโm working, I can have a flashy or interesting lighting mode active to keep my mood up, but when Iโm gaming I can have a mode which doesnโt just look good, but which actively improves my overall experience.
In addition to this, it is possible to program macros into the keyboard on the fly. Whilst I donโt personally use them often, I can definitely see the appeal of them for some gamers, and whilst itโs a difficult system to figure out alone, within just a few minutes of viewing the keyboardโs video manual you can easily program a variety of functions to your keys. Unfortunately, for some reason there is no way to customise these macroโs using the pc itself, but once you know what youโre doing it isnโt too difficult. My only gripe on this note is the fact that there are no extra keys specifically for macros. However saying that, I canโt think of a single game which uses EVERY key on the keyboard, so Iโm sure you could find at least one of them to reprogram, even if itโs one of the F1-12 keys.
One last thing; alongside all of these customisation options, thereโs also a lighting mode with lets you play a simplified version of the classic game โSnakeโ. I certainly wasnโt expecting it, but itโs a fun distraction whilst youโre waiting for your Fallout 4 save to load.
Into the breach!
As previously mentioned, the Masterkeys enriches gaming through itโs lighting and macro capabilities, but the question remains; how good is it as an actual keyboard.
Very good, as it stands. Iโve been sitting here typing for hours and my fingers feel fine, just as they have during my recently long gameplay sessions. It isnโt the deepest board, but itโs still pretty sensitive, with the Cherry brown switches giving a satisfyingly tactile click when you press. Itโs relatively quiet as far as mechanical keyboards go, but still reacts instantly during gameplay.
I would only argue that if youโre a lazy typist who rests their wrist on the desk (like me,) a wrist-rest is a must, as itโs quite a high โboard. In some ways Iโm glad that they didnโt include an attached rest on the keyboard, as it allows me to get my Fellowes Gel wrist rest closer to it for better support.
It feels good; really good, with quality oozing from every key-press. Whilst some keyboard make writing, typing and reviewing a chore, this one makes it a pleasure which Iโm happy to indulge.
Final Verdict
The Coolermaster Masterkeys Pro L keyboard is an absolute beauty. From concept to execution, it does everything a young, gaming professional could need and more, and in some ways itโs a product of two halves. It can be subtle or loud, acting sensibly in public but exploding in a fountain of vibrancy and colour when you want it to. It works well as an overall typing device, providing excellent finger-comfort and tactile recognition whilst still being a gaming beast with macro functionality. It covers all bases excellently and with style, with my only slight complaints being the lack of software-based macro customisation and a volume roller. Realistically though, those are only arbitrary complaints, covered satisfactorily by other means. Iโm not saying itโs a perfect keyboard, but it comes damn close.
Yes, the Masterkeys Pro L has a hefty price tag, but you get what you pay for and itโs worth every penny.
