When we first pulled the keyboard out of the box, we were super excited to give it a try. Once on the desk, and trying to go right into writing a review, we lasted about ten minutes and gave up on the SK621. The Shift key size was causing too many problems. However, as a reviewer, we cannot just give up and return the product, we have to work through issues, and we are glad we did. Once used to the SK621, we not only get to use a near-silent keyboard, and even though linear switches aren't our preferred switches, we now have a tough decision. Do we stick with the favored Fnatic Mini STREAK, or do we move to the SK621 as our daily driver? This says a lot about a keyboard, as we tend to keep the best of the best on our desk, while the more mundane offerings are donated to those in need. For the SK621 to have us so far off our game, and come back to win our hearts, we have to give it to Cooler Master, as they have given us a whole new outlook on input devices.
The feature set is full, and anything you could want is possible to be done with the SK621. Multiple profiles, the ability to add and remove them at will, lighting controls, full Macro support, anti-ghosting, NKRO support, multimedia keys, it's all right there on the keyboard. For those of you who would rather not clunk around with the Function key and multiple keys after to get things done, there is always the option to use the Cooler Master Portal software, which can do all of what the keyboard offers in a convenient window, where all things can be done with much less effort. We love that there is so much onboard memory as well, which allows the user to go into Portal, program it till things are perfect, and store it all right on the keyboard. This way, when it goes back in the velvet bag for travels, you can slap it on the desk, and it is ready with all of the same options you left home with. A huge selling point to many users is the wireless feature. While we have seen a few full-sized and TKL versions of keyboards that are wireless or Bluetooth capable, if you want a smaller option, they tend to be very small. The SK621 and its 60% form factor make this an excellent middle-ground for those that still want standard-sized keys, but do not want to stick a bigger keyboard on the coffee table or in a drawer. We have to admit; the SK621 is all it was cracked up to be, and a little more.
In the beginning, we did feel that the cost of the SK621 was a bit on the high side, but that perspective has changed. Considering everything that is possible with this keyboard, considering all of the features, the length of battery charge time, the ease of the Portal software to customize the keyboard for those not wanting to try it on-the-fly, and the lack of room needed for it on the desktop are all huge factors that play into it. At $119.99 it won't win any prizes for dollar per square inch of keyboard or cost per pound of weight, but even so, for such a small device, the SK621 is worth every penny. We have seen many larger keyboards with half the features cost this much, and let's be honest, there is a bit of a freak-out factor that comes along with the SK621 when all of your friends see what you use, and that is always fun. The SK621 Compact 60% Mechanical Wireless Keyboard may take a bit of getting used to, but the effort is worth our initial frustrations. For those looking for the perfect travel mate, or those looking for a keyboard for the living room, even those just looking for the basics without eating up a ton of desk space, Cooler Master has the solution, and we strongly urge you to give it serious consideration, and not let the compact design get you down. The SK621 can do anything the big boys do; it just does things a bit differently.

The Bottom Line
The compact nature does give off a bit of sticker shock initially, but once you see and use the feature set, and get used to the layout of the keys, the SK621 overshadows any doubts in cost. While not a device everyone will gravitate towards, those who do will be rewarded for their choice!
