Cooler Master MasterKeys Pro L RGB Mechanical Gaming Keyboard 'Full Size, Cherry MX Brown Switches, RGB LED' SGK-6020-KKCM1-UK

This is my first mechanical keyboard, and I have to say it is worth every penny. The first thing I noticed is the build quality and how heavy it feels. It is far supperior than any membrane keyboard. The Cherry MX Brown switches are great and feel very nice, not too loud. It is comfortable to type and the design is simplistic and thats why I like it rather than a gamery type mechanical keyboard. The colours are very nice and bright enough. Also, the software is easy to use and there a lot of customizable settings, especially the one I like is the equlizer that reacts to music you listen. My pc recognized the keyboard the second I plugged it in and didn't have any issues. Overall I am very pleased of this product and I think it's a great keyboard to upgrade to.

This keyboard is actually my first mechanical, & I didn’t want to cheap out so I knew I had to pay more than you’re average consumer would consider acceptable. First off, the build quality is a lot better than I expected. Not a single rattle from any keys aside from the space bar, but even that isn’t bad by any means. I prefer the subtle design of Cooler Master over a more aggressive style from others like Logitech & Corsair. The keys have a nice font & they feel nice & chunky plus a key cap pulled is included. They’re pretty smooth keys though which is my only gripe. The RGB backlighting works fine, but the light doesn’t shine through the entire key along the number row, only the top part, this being because each key only has 1 led at the top end of the switch. You can control the entire array using just the keyboard, no software required which is great. Macros are available too but I haven’t expermented with any of that. The keyboard feels solid & sturdy with rubber-tipped kickstands & small cable channels running underneath for different cable management options. I would recommend this to anyone looking to upgrade their keyboard to a fancy gaming RGB mechanical but doesn’t really like the OTT style that comes with a lot of the others.

The keyboard itself is great with plenty of customization and nice colour options but there is an issue with it. When I ordered it, the keyboard arrived and the "L" key wasn't working properly - it wouldn't register the key stroke properly, sometimes even after slowly pressing the key from top to bottom. Switching physical keys didn't solve it, and even when I tried pressing the switch directly, by taking the key off, it didn't work so I assumed it was the switch or the connection between the switch onward at fault. I requested a replacement, which took a long while to arrive. And with the second one, the L key worked! But the left "Ctrl" key now had the same problem. Half the time it just doesn't register the stroke at all. As this is a gaming keyboard this is not acceptable. Let me re-phrase this: as this is a keyboard, this is not acceptable. I've never come across a keyboard, no matter how cheap or dear, that would have these problems and for the same problem to appear on two separate keys on two separate keyboards is just amazing. Don't think I'll be buying from Cooler Master again.

From the moment it landed on my desk I've been clacking away on it and I'm very impressed. It feels awesome to type on and all the keys register my presses perfectly - way more sensitive than my rubber dome keyboard. The case is very solid and has a nice weighty feeling to it, and the USB cable is removable with 3 potential guide-channels (left, right and rear) for good desk placement.Lighting-wise there are a ton of options, and it can be manipulated via software or using the function keys on the keyboard (very shallow learning curve too). My only gripe is that the scroll, caps and num lock keys do not illuminate when they are not on, meaning scroll and caps are off almost all the time. Hopefully this will be addressed in a future update to the software.As opposed to other reviewers, I have not had any issues with dead keys so presumably the issue is now resolved.

Overall this is a very good keyboard and I'm happy now I finally have one that works as it should.The ProsThe bezel is small, there is no superfluous space on the case, and this keeps the dimensions small for a full size keyboard. It feels solidly built and the plastic isn't flimsy. The switches (cherry mx brown) are good and while the keycaps aren't perfect they're good enough. The RGB LEDs are bright and the colours really shine through, in no small part thanks to the white backplate. The software to set up your colour profiles is relatively easy and straightforward to use. Having a removable cable is nice, and the cable routing for centre, left or right alignment is handy.The ConsMy first Masterkeys Pro L (technically my second as the first one I ordered Amazon Logistics lost en route!) had a faulty switch under the 'w' key. With seeing reports of others having similar issues, especially with LShift I have concerns over the quality control of the first batch of boards.I do feel like the four profile keys could have pulled dual purpose, perhaps for custom keybinds/program launchers with the profiles on the Fn layer. They seem a little bit of a waste of space for me as I'm not likely to want to switch profiles that often.Overall I'm very happy with the board so far.
