Cooler Master CK720 65% Gaming Keyboard Review

Nearly a year ago we took a look at the Cooler Master CK721 Wireless Mechanical Keyboard, and today we are back with a look at a very similar, yet very different keyboard – the CK720. Now you might be thinking, surely this is a downgrade from the CK721 because of the name, but I would say that this is quite the opposite. While these two keyboards have a lot in common, the CK721 has a nice list of upgrades that could make this the keyboard of choice from Cooler Master for those wanting to get into the world of mechanical keyboards with more than the bare minimums.

Special thanks to Cooler Master for providing the CK720 review sample!

The CK720 comes packed in a standard retail box, with product imagery and features highlights, on both the front and the back, as one would expect. The front has a more prominent image of the keyboard, along with a few feature notes.

The backside gives a more detailed view of the keyboard, including a bit of an “exploded” look at the keycaps and hot-swappable switches.

Cooler Master provided the CK720 with a nice and compact box interior that does a great job of protecting the keyboard during transportation, and keeps the included accessories snugly in their place.

Included with the keyboard is a 1.8m rubber USB-A to USB-C cable, keycap and switch puller, eight Cherry MX Green switches, and a Quick Start Guide and instructions on how to remove the top cover.
