Not that long ago we took a look at Cooler Master’s SK630 low-profile mechanical keyboard, which was a tenkeyless keyboard that featured Cherry MX low-profile mechanical key switches. We loved this keyboard and felt it was perfect for someone who does a lot of typing rather than gaming. Today Cooler Master is releasing their SK621, which is even smaller! It is a 60% keyboard that features the same low-profile Cherry MX mechanical key switches, sleek design, and RGB lighting, but now offers hybrid connectivity (Bluetooth & wired) making it the first wireless keyboard from Cooler Master in their SK series. Could this be the ultimate keyboard for the mechanical keyboard enthusiast or programmer? Read on as we find out!
Special thanks to Cooler Master for providing us with the SK621 Low Profile Keyboard to review.

Packaging
The SK621 comes in Cooler Master’s typical retail packaging we’ve seen for their SK Series keyboards. On the front of the box is a photo of the keyboard and it lets us know the keyboard is Bluetooth, RGB, and features Cherry MX low profile switches.
Flipping the box over to the back there is another picture of the keyboard and some of the main features are detailed.
Opening the box up and getting everything out we have the SK621 keyboard, which comes in a small bag that you could use as a “travel bag” for the keyboard, a USB to USB-C cable, keycap remover, and a user’s guide.
