Cooler Master SK620 60% Space Gray Mechanical Low Profile Gaming Keyboard, Mechanical Red Switches, Customizable RGB, Ergonomic Design, USB-C Connectivity, Mac/Windows

This keyboard as of right now is one of the few bluetooth keyboards offered by a mainstream producer that is actually in stock. Firstly the Pro's. USB-C Charging is really convenient. Its small size and no need for a wire makes it really convenient on my desk. the switches are consistent and feel good to type on. and the battery life is... fair? i get about three days of use with the backlight on. However the cons heavily outweigh the pros. The key caps although improved from last years SK621 model are simply too busy. every single one as a secondary command that makes the keyboard feel awkward and is not so easy on the eyes. But what ruins this keyboard more than anything else is the connectivity. i have the bluetooth dongle mere inches from the keyboard with a direct line of sight. Yet its latency in games varies from unnoticeable to simply unplayable. getting stuck walking in directions. massive delay. and just generally a bad experience. even sometimes when typing it will get stuck and just start repeating a letter in a long string until it resolves itself. Personally. i'd say avoid if you have any other option.

It feels well built. Nice overall typing experience when I first got it. The red switches are linear mechanical. It takes a little getting used to the layout and size.I bought this for use on a media PC. You can pair 3 devices or plug in the included USB cable. Currently, I have my media PC and an Android tablet paired.Be sure to check for software updates. There were a few intermittent issues such as Bluetooth disconnections and repeatinggggggg characters but these seem to have gone since an update. Only been a day so I'll update this review if there are still problems.* A few days later *I got the occasional repeating characters so I plugged the Bluetooth dongle into a USB hub. It's slightly closer but I think that the real difference is that the dongle is now at a different angle and that helps the antenna. Just a theory though.* Months later *Sending mine back as the F and O keys work intermittently. They work if I press them much harder. Shame as I liked other parts off the keyboard.

Don't be tricked by the discount like me! A big problem with this is the design of the USB-C port it's regressed in a way that only the supplied USB-cable can fit. You'll need to buy a slim profile type C cable if you don't want a dead keyboard if you lose the one supplied. Another problem is the over complexity of the FN keys. Unless you spend a deal of time learning all the short keys you run the risk of freezing the board as it records and macros. Really wanted to like this as the low profile wireless mechanical concept ticks all my boxes. Shame Coolmaster is unable to deliver.

Well packaged, backlighting is great, adjustable feet help get the right typing angle (although they only give one setting)This was my first mech coming from a MacBook keyboard & the transition was easy. You can buy a wrist rest separately from CM for this board, but have had no fatigue from not using oneOnly downside is you need to take it apart to lube the stabs, but honesty if you are buying this that’s probably not something you care about too much.It’s well packaged, comes with a quick start guide and a nice velvet bag to keep the dust off it. I don’t believe the 10-key rollover works on wireless mode, but no problems going wired. Comes with a braided cable too :)Have had some small latency issues when plugged in using the wireless mode, but have since moved my pc and the 2 foot change seems to have made all the differenceThis is a clacker not a thocker, but it’s a budget low profile with abs caps and an aluminium plateWould recommend, especially for those looking to try a mech board from laptop keyboards. Nice job cooler master :)

The media could not be loaded.  Hello,I am very satisfied and proud to comment on this product. The linear red switches you get feel smooth and almost buttery matching those of higher end keyboards. When I buy from Coolermaster I always know that I am getting quality and value for the money and this is no exception. The keyboard is extremely light(446g) and packs 2x2000mah batteries. This means the keyboard can last up to 3 days of total use, probably without the rgb turned on so with them on it would be like 1 day and a half so 36 hours, which is pretty decent. Also would like to point out this company listens to fan feedback and acts on it, that is why they deserve your money above all - the previous model keyboard of this, the sk620/1 had controversial flat keycaps and they offered anyone with that model free improved ergonomic keycap replacements. No one does that, believe me.

If you don't use right side shift, this is a good keyboard. For those, who are pressing shift key at the bottom left corner of the ISO enter key, you are to avoid this abomination, the up arrow is there, will annoy you a lot. The absolutely useless DEL key just for ecstatics is also questionable, but not as annoying as the shift.

Very poor Bluetooth performance. I bought it as a secondary keyboard for times when I need desk space and it has failed me repeatedly. DO NOT BUY.

Well, after trying this out for a few weeks the verdict is mediocre. After all, this is advertised as one of the top-end small keyboards. I don't think it is. The Bluetooth sometimes has a very bad lag, just for normal typing, as for gaming, forget it. OK, it does fine wired, but so does a £10 keyboard. IMO it's not worth the money.
