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.
