Cooler Master, 65% size keyboard CK721 dual wireless & wired
Cooler Master will begin handling the tiny mechanical keyboard "CK721" series for the local market. The CK721 series enables dual wireless and cable connections. On February 18th, two distinct color versions of the "CK721 Gray" and "CK721 White" will be introduced.
A ten-keyless mechanical keyboard with a 65 percent smaller layout than the full version. Additionally to 2.4GHz and Bluetooth dual wireless, the connection interface enables wired USB. Additionally, the key switch features a brown TTC mechanical switch shaft.
The keyboard layout is in English, and the primary keys are supplemented by arrow keys and a few function keys (Delete / Page Up / Page Down). On the upper right of the main unit is a three-way rotary encoder, which may be used to execute various functions such as volume adjustment and LED emission pattern switching. The "MasterPlus +" software can be used to assign functions.
Additionally, it features an on-the-fly customization option that enables you to record macros, alter the illumination, and change the emission pattern with a few keystrokes. For 2.4GHz wireless and cable connections, the polling rate is 1,000Hz (1ms), but for Bluetooth connections, the polling rate is 125Hz (8ms). It comes with a built-in 2,000mAh battery that lasts up to 73 hours.
External dimensions are 334 mm in width, 118 mm in depth, 37-46 mm in height, and 764 g in weight. The base of the main unit features a two-stage tilt stand, and you may choose from three different angles, including the flat position.

I like the less gamery design of this kb, but the gaping hole on the left side make it looks cheap.
I'd rather go with Keychron Q2 if I want to use 65% with knob.
It has a cover. The hole is used to access the release for the interchangeable top plate.

If it were hotswappable as well it would have been an awesome little keyboard, I'd never buy a keyboard with soldered switches ever again.

Looks cool for portability would be good for Lan parties or just using on a laptop
