Customers find the keyboard's compact design and color range appealing, particularly appreciating the customizable RGB lighting options. However, the functionality receives mixed feedback - while the wired connection works well, the Bluetooth mode is often laggy. Moreover, the keyboard quality, switch functionality, and value for money draw mixed reactions, with some finding it great while others report it stops working properly after three months and has horrible switches. The brightness also gets mixed reviews, with some praising the backlight while others find it not bright enough.

Almost Had Me In The First Half - Now I’m Obsessed

- Reviewed in the United States on April 6, 2022Size: 60% WiredStyle: SK620 Sliver WhiteColor: Gunmetal Black, Silver WhiteVerified PurchaseTLDR; it hits all the marks I wanted in a keyboard: low profile, good build, mechanical, 60% , white color, good price.
I was on the hunt for a reasonably priced, $80 or below, LOW profile mechanical gaming keyboard in white. Surprisingly hard to find, especially from a brand I've actually heard of...
I wanted low profile because it does make a it easier on your wrist angle and also they are slightly faster to actuate the key.
Glad I ran into the sk620. It hits everything. Now I'm not a keyboard enthusiast so the sound and feel of switches isn't my specialty. I ordered the red and brown style, I ended up sticking with the brown. They were less "sharp?" sounding and some of the keys on the red were louder than others. Could of been a bad run? The browns were more uniform across all keys. I recorded some decibel readings and the browns were quieter by 1 or 2 db, so not much but some . ALSO because it's so low profile and a 60% size I think having very small tactile feedback from the browns helps a bit to feel confident in your press. The red was almost too fast and easy to click other keys on accident.
The size takes some getting used to, but it's all muscle memory you get a hang of it coming from a full size. Biggest thing is the right side shift key is smaller and the delete key is next to the arrow keys. Anyone in the market for a 60% should know youll have to adapt a bit. But
for gaming it's such a nice size.
For general typing the keyboard is accurate and snappy, I hit 81wpm with 97% accuracy which for me is my fastest yet. It is louder than a normal membrane keyboard, so just realize that, just cause its low profile doesn't make it that much quieter than the full size
Build quality feels solid enough, has a metal top plate, good rubber feet and height adjustable. The keycaps are ABS but they seem really well coated compared to my older keyboards with a nice matte texture.
Cable is braided and color matched, uses USB-C which is great to see. You also get a keycap puller in the box to make it easier if you need to remove any.
RGB is great and bright, with a LOT of customization options in the software. Also in there you can set macros and disable/remap keys which is incredible handy.
- Reviewed in the United States on September 11, 2022Size: Full WirelessStyle: SK653 GunmetalColor: Red SwitchVerified PurchaseI've had this keyboard for more than a year now so I can safely say the following review is not at all as a result of me just not giving it a chance or not having had time to get used to it or anything of the kind.
Now with that out of the way,
THIS IS THE WORST PILE OF GARBAGE KEYBOARD I HAVE EVER OWNED IN MY ENTIRE LIFE.
This keyboard is complete TRASH. Where to begin, there's just SO many things wrong with this keyboard it's hard to even put it into words. For starters, the keyboard does not work at all until after your OS boots and bluetooth drivers load. The keyboard connects via bluetooth so you CAN NOT use it for anything pre-boot. Need to get into BIOS? TOUGH LUCK SCRUB. Your PC will not register your key presses prior to your OS loading up. Also I'm sure I know what you're thinking. "You have the option to connect via USB as well..." THAT ALSO DOESN'T WORK! It doesn't matter if you're connected wirelessly or via USB. It will NOT work at all until your OS is completely booted. Making this keyboard worthless just for that alone. What a joke. Even my cheap $10 logitech keyboard I've had for over a decade works flawless to this day. Thankfully I have it so I can get into bios as a backup when I need to.
Next up, the "features" this keyboard comes with. They're AWFUL. Coolermaster just loaded it up with TONS of worthless features that no one needs which GET IN YOUR WAY ALL THE TIME!!! And It has mac and windows mode? Are you STUPID!? If I wanted a mac keyboard I'd get one. This is absurd. You have no idea how many times I accidentally switch to mac mode without even realizing it because of the stupid keyboard combinations that you use to control EVERYTHING. Then I wonder why nothing is working anymore and of course it's because I'm in OSX mode. UGH.
And on the topic of keyboard combinations, there are SO MANY combinations!!! It's impossible to remember them all! But what happens if you press a combination by accident or your cat walks on your keyboard or whatever and all of a sudden everything's messed up? Well good luck getting it back to how you want it because of how many keyboard combinations there are that aren't clear at all on how to use them. And you wanna look up what they all are? Good luck with that too because cooler master's on product support page is worthless and doesn't have documentation on it at all!!!!!!
And if that's not bad enough the software is completely worthless too. Just overall complete trash. I would regret getting this keyboard even if I'd gotten it for free. But I had to pay over $160 for it. Almost two hundred dollars for a keyboard that makes me wish I was on literally anything else every single day.
What a shame because the actual mechanics of this keyboard are actually good. It's nice and simple (the layout) the keys feel good, the build quality is solid and the backlight is VERY good. But everything above just completely invalidates an otherwise solidly built keyboard. Just goes to show some people just can't help themselves. They over complicate something as simple as a keyboard and end up releasing a steaming pile of garbage.
DO NOT BUY THIS KEYBOARD. STAY AWAY!!!!

4.0 out of 5 stars Singapore Buyers! This is the BLUE switch version! Do take note!
Size: 60% WirelessStyle: SK622 Sliver WhiteColor: Blue SwitchVerified PurchaseDescription says Red key switches, which was what I really wanted as my wife does not like the sound of clicking keyboards. As stated by another reviewer in SG, I received the Blue switch version. 1 star knocked off.
Coming to the SK622 itself, I can honestly find no fault with it. It has RGB, mechanical key switches, it works in both wired AND wireless (Bluetooth), and is built well. Oh, comes with a nifty little black bag to store it in too.
And that little black bag is where the SK622 is currently staying in. I decided not to return it as I did buy it for a really good price and after all the product does work as intended. I'll just hold on to it and find another use case for it. Amazon, you really need to edit the product listing.

5.0 out of 5 stars Low profile wireless RBG bliss!
Size: 60% WirelessStyle: SK622 GunmetalColor: BlackVerified PurchaseI don't usually write reviews but I was so pleased with this keyboard, I had to!
Low profile switches? Check. No twangy metallic sound upon a keystroke? None whatsoever. Wireless capability? Has it. Excellent RGB? Some of the best to date IMO.
This is a superb little keyboard. It has a remarkably small footprint on the desk but doesn't feel cramped to type on whatsoever. Highly portable for on the go use, too. Blue clicky is of course the loudest switch type, so don't be expecting a quiet keyboard, but this rendition is not excessively loud. If sound isn't an issue, try blue switches. They feel awesome and responsive; there is a type-writer kind of satisfaction to using them.
Cooler Master delivered a really solid little unit with this guy, and its very hard to find all of these elements in one keyboard at this price point. Solidly built and a pleasure to use. If you're looking for a 60% keyboard, or are interested in trying one, this is a stellar option.

5.0 out of 5 stars No issues here
Size: Full WirelessStyle: SK653 GunmetalColor: Brown SwitchVerified PurchaseBought purely for the lit keys, and size with included num pad. Custom setup is nice to have and already used a few functions which has been super helpful. Key strokes are noisey but some people may like that. Bit pricey but I happy
- ErikaReviewed in Canada on February 25, 2022
2.0 out of 5 stars Enter and Backspace buttons don’t always work
Size: Full WirelessStyle: SK653 Sliver WhiteColor: Brown SwitchVerified PurchaseI bought this so that I can use it for my mac and my PC but for some reason there are times where even if I press the backspace or enter button 10 times, it will only register once. I’ve never dealt with something so annoying for a $150+ cad keyboard before. It’s a shame because otherwise it looks so pretty.
