Cooler Master's New Wireless Mechanical Keyboard is Crazy Thin

They say you can't take it with you and, when it comes to mechanical keyboards, they are usually right. While there's nothing like the feel of a good mechanical keyboard on your desk, just try sticking it in your bag to carry with you on the road. Enter Cooler Master's CK620. Due out at the end of this year or in early 2019, this amazingly-compact mechanical keyboard can fit into most handbags and has an optional Bluetooth connection.

The CK620 is one of the thinnest mechanical keyboards around thanks to Cherry's new, low-profile red switches. Red switches, particularly those from Cherry, have long been prized among gamers for their quick response time. These low-profile switches are 35-percent thinner than their regular counterparts, yet still have the great mechanical feel that power users crave.

Overall, the Cooler Master CK620 is 60 percent the size of a full keyboard and much more compact than a typical tenkeyless keyboard. Even the key caps are optimized for space-saving, because they are completely flat. 

I had the chance to spend a few minutes with the CK620 and was really impressed with just how great it looks and feels. The keys appeared to have plenty of travel and were more than large enough for adult fingers. They had the snappiness you expect from a mechanical keyboard too. 

Even with all the space-saving, Coolermaster found room for beautiful RGB lights which create a dazzling show. The silver base and black keys round out this impressive package.

A Cooler Master rep said that, when it launches at the end of this year or early next year, the CK620 will be available in both a wired-only and a model that can connect via Bluetooth and USB Type-C. They said to expect a modest five hours of battery life with the RGB lights on, but a good deal more with the lights off.

In addition to the CK620, Cooler Master is coming out with two other low-profile keyboards. The CK630 is a less-compact, tenkeyless model that has more blank space around the arrow keys. The CK640 is a full-size keyboard with numpad.

    Its a keyboard? Not to mention generally I've found hardware support to be better in Linux than Windows. Many things that require special drivers in Windows or only work in certain versions of Windows, just work in Linux.

    To answer your question any mechanical keyboard will work fine Linux. The problem you will run into is setting up LEDs or macro keys, that stuff likely won't work, or will be stuck with the default config (Perhaps this is what you were actually asking?). Unfortunately for that you'll have to temporarily plug into a Windows machine for setup if you must change it.

    I've had a WASD keyboard for quite some time now, with TUX keys instead of Windows keys:

    Five hours of battery life with the RGB lights on is really modest!!!!!

    Pff, look at those lose keys...... Low profile keys ar good, but only in keyboards that protect them, not like this one. It looks like you can break them even if you press too hard... :(

    I want to like it, but... I waited a long time for a 10 keyless wireless illuminated gaming keyboard. :((
    I really really want a Logitech G PRO 10 keyless keyboard, made wireless!! <3 <3 <3
