Cooler Master CK721 65% Hybrid Wireless Gaming Keyboard Review

There was a time when micro keyboards existed only on the periphery of the pc world. Today tenkeyless or TKL designs are rapidly gaining market share with 65% designs leading the charge.  Today we will be looking at Cooler Master’s CK721 65% Hybrid Wireless Gaming Keyboard.

The CK721 is not just a smaller form factor, it also a host of additional features including wired and wireless connectivity, mechanical keys, customizable cover and oodles of RGB.

Let’s take a closer look!

The Cooler Master CK721 featured in this review is the Space Gray color but, can also be found in an attractive Silver White.  Keycap options from TTC include the linear Red (that we have), a more clicky Blue and a tactile Brown.  TTC Switches are often marketed as an affordable alternative to the pricier keycaps like Cherry MX switches while still offering a solid mechanical feel.
