Cooler Master have a smaller 60% keyboard as well as a full sized mechanical keyboard that’s wireless too but the CK721 falls in the specific niche between those devices.

Unboxing the keyboard, users will notice the spongy low-friction cloth covered wrist rest straight away. This wrist rest is soft to the touch and will be highly appreciated by gamers who spend extended periods of time at their keyboards. The only gripe with the wrist rest lies with the fact that it’s prone to getting dirty very quickly. This wrist rest is a dust and grime magnet and even though it’s darkly coloured, you can notice the dirt it picks up just from daily usage.
This wrist rest is soft to the touch and will be highly appreciated by gamers who spend extended periods of time at their keyboards.
It should be noted though that the polling rate is different when using Bluetooth though at only 125 Hz whereas it’s a solid 1000 Hz in both the wired and 2.4 GHz wireless modes.
This dial is useful for gamers who want to set it up to perform specific tasks such as skipping songs, adjusting their PC volume, adjusting the keyboard’s RGB brightness and more.
Gamer, writer, self-proclaimed chemistry hobo. Always looking to make use of a good pun in the name of fun.
