The first look at the SK621 is of the left edge, where we see exposed switch bodies under low-profile keycaps above the aluminum top plate. As we make it a bit further down, we see the bright angled edge of the diamond cut aluminum, with a matte trim ring under that. The lower section is made of textured black plastic, and between the two parts of the frame, there is an opaque layer of plastic, which is illuminated with LEDs independent of the switches. Within the plastic lower section, there is a switch, and this is how you enable the Bluetooth feature.

We wanted everyone to have a full grasp on what the SK621 is, and just how small the layout is, and yes, this is all of the keyboard. Gone are the number pad, commands, and arrows, all in favor of a much more compact design, where most of the keys do double, if not triple, duty. At this time, we should also mention the brushed aluminum top plate, as well as the flat tops to all of the keycaps.

To make it easier to see, we stepped in much closer so that it is easier to see the functionality, even with a severe lack of keys. In the top row, the F-keys are doubled with the number keys, while the second row deals mostly with lighting. Row three deals in Macros and how they are to be used, and row four is where the Bluetooth devices can be selected, and which keyboard profile is in use.

The right half of the keyboard delivers functionality that was lost due to the compact nature of the SK621. All of the commands are present, the arrow keys are there, and the arrows also let you adjust the direction and rate of the LED modes. There are even a few keys that will help with the volume. And a Windows lock function on the Backspace key.

Typically, when we look at the right edge of the keyboard, we make sure to extend the feet on the underside, but the SK621 does not have any. The angle you see now is it, although, we do like the forward lean to the row of caps.

On the back edge of the keyboard, within the lower plastic frame section, is where the USB Type-C connection from the cable is made to the keyboard. We like that Cooler Master moved to USB Type-C, as we have fought to connect many motherboard detachable cables in the past, and with this, the orientation of the cable means nothing. It will still connect without any of that hassle.

Under the SK621, we see a Cooler Master logo indented into the frame, while safety and compliance notifications are etched into the plastic. Below the both of them is the product sticker which will be handy if an issue does turn up, and to support the keyboard, Cooler Master opts for four rubber feet, as far into the corners of the keyboard, as possible.

As an avid overclocker, Chad is always looking for the next leg up in RAM, cooling, as well as peripherals.
