Cooler Master Sk-621-Gklr1-US SK621 60% Mechanical Keyboard with Cherry MX Low Profile Switches and Brushed Aluminum Design

I originally bought this keyboard to use with the iPad Pro but ended up using it for all my devices, including my laptop and desktop. You can switch between devices quickly with simple key combinations. If you are expecting a traditional keyboard then this keyboard may not be for you. YOU WILL NEED TO ADJUST TO THIS KEYBOARD since some of the keys are of different size i.e. the right shift key, the del key to the right of the up arrow. Other than that, it feels like I'm typing on my laptop keyboard except the travel is a tad longer. This keyboard is not a "clicky" keyboard and is soft to the touch; some may like this, some may hate this. All the keys are accessible, however, you may need to press key combinations to get them; for instance, to type the "tilde," you must press the key combination FN+SHIFT+ESC, and for the "tick," you must press FN+ESC. (Not sure yet if you can map to different keys). There are, in fact, dozens of built-in macros: for music control, profile switching, lighting, macro recording, etc. I can't recommend this for everyone unless you're willing to change some habits. Personally, I love all the options and freedom (portability) this keyboard provides. Disclaimer: This review was typed using the SK621.

Really solid keyboard; feels great to use, although it takes some getting used to. My only beef with it is that the Bluetooth function becomes ineffectual at more than 2-3 feet away. My gaming setup is in my bedroom - 4k TV so I lay on my bed approx. 6 ft away. Bluetooth is garbage at 6 feet away apparently for keyboards even for regular typing, let alone gaming; so much latency. Fortunately the included USB-C cable is long enough to reach so I can use wired mode, which works flawlessly (plug and play). In short, this is a great keyboard that feels really satisfying to type on (despite the learning curve due to its size). However, don't expect the wireless mode to be useful if that's what you're getting this for.

Like many of you guys, I thought this would be the perfect keyboard for me, as a very fast laptop typist, so much so that I ignored the hundreds of reviews laying out all the problems with this product. It was a mistake. This is not a good keyboard.Let's start with the good: the build quality on this thing is fantastic. Some of the best I've ever seen on a keyboard. And it's beautiful to look at, too.As for typing—it's a nightmare. I had read that there was a problem with the keycaps and that they had fixed them, but I didn't realize that you still needed to special order (for free, although there is no delivery window given and I assume it will take weeks before I get my replacement) the new/better keycaps, and that the boxed version here on Amazon still ships with the original caps. It is *nearly impossible* to type accurately on the default keycaps. I'm someone who can put out 120+ wpm on a laptop keyboard, and nearly as much on a long throw mechanical keyboard. On this thing, after a bunch of practice, I was able to hit 78 without errors. The problem is that the caps are all super close together, and due to the nature of the switch design, you will readily actuate multiple keys at once, so you just end up typing *super* sloppy. Plus, the short throw red switches just feel awful to type on regardless. They are mushy and bleh. No keycap can fix a mediocre switch.There are also some layout annoyances, like the tiny right shift button, plus a confusingly designed Caps Lock LED which actually indicates that bluetooth is connected (!).The bluetooth on this thing sucks. It takes 10-15 seconds to connect, compared to my former "unknown Chinese brand" keyboard which would (and still does) connect within a second.The included software is a nightmare. Good luck actually getting the settings you want to stick, and then attempting to navigate your way through all of the different shortcuts on the keyboard that don't come with any documentation in the box (you have to dig through their website to find it), and even once you know what they do, they don't work half the time anyway. The best part is that as you are changing settings, all sorts of LED sequences on the keyboard light up as if they've some kind of confirmation, but good luck figuring out whatever CM is trying to tell us with these undocumented sequences of lights.Lastly, the (lack of) angle on the device is bad, especially with the grippy and too-close-together keycaps. It feels like you have to bend your wrist over to properly type in such a fashion as to not constantly double up on keystrokes, which is terrible for your wrist.

This is a very attractive keyboard and feels extremely well-constructed. It's hefty and solid.Others have complained about the keycaps. They're both completely flat and extremely close together, which will probably demolish your accuracy at least until you get used to them if you ever manage to get used to them.What really makes it a do-not-buy, though, is the bluetooth connectivity. You're paying for a keyboard with multi-device bluetooth and a battery -- you can get an equivalent wired keyboard for less money. But the bluetooth is so bad it's completely unusable. Even when I'm using it on my desk six inches from my laptop with nothing but clear sky between the laptop and the keyboard, it cannot maintain a connection. Input lags *multiple seconds* and the connection drops frequently. Can I plug it in and use it in wired mode? Sure. Should I have to? No. If I wanted a wired keyboard I would have bought one.I have the same issues on two laptops and a desktop, and I use multiple other bluetooth devices on all three without any problem, including the keyboard I'm using to type this review (if I'd tried to type the review on the SK621 it would be riddled with typos and it would take me an hour).

This keyboard is amazing. I love the way it sounds, the low key caps, and the size. The right shift key is a little small but i think that is something I will get used to through use...my boyfriend is planning to buy one soon too because he likes it so much!
