What you need to know

  • Cooler Master's new CK721 mechanical keyboard claims to be good for up to 50 million keystrokes.
  • It can connect via Bluetooth, 5.1, 2.4 GHz, or USB type-C.
  • It's compatible with the vast majority of modern operating systems and releases on March 29 for $119.

Even though it's a 65% form factor keyboard, leaving it small compared to some of the competition, the CK721 goes big on features. For starters, it's compatible with just about any operating system you're likely to want to use — including Windows 8.

You read that right: Cooler Master is voluntarily namedropping Windows 8. So if you're one of the diehards still sticking by that OS, this keyboard will treat you right, just like it will if you're on Windows 11 or 10 (but not Windows 9), Mac OS X, iOS, or even Android. No matter where you need a proper keyboard, the CK721 will be ready for action.

Furthermore, this little typer comes with RGB flair, a wrist rest, and a precision dial to help you more easily fine-tune your keyboarding experience. It has just about everything one could want, so long as one doesn't want anything the CK721 does not offer.

The $119 keyboard is not yet released, so don't even think about getting excited over the prospect of buying it. But do think about getting excited over preordering, since you can do that between now and its March 29 release.
