Ok keyboard, but has some flaws. Sometimes stops working and have to cycle through the wired/wireless mode to get it back.
It would have been much better if there was no bluetooth at all, simply usb keyboard, or wireless with usb dongle would be nice maybe but bluetooth is sh1t.
The usb plug on the back of the keyboard has no space for cable management like other keyboards do. Also the plug is inside a hole a bit too small for standard cables, so have to use the original cable only and even that one takes a long time to manage to plug it in. It is usb-c, but it is at a slight angle which makes the connection a pain. Because of the size of the hole, you cannot use one of those magnetic cable with USB-c adapter either.
RGB lighting is ok I guess if you are into it. For me, I think it is way too many modes, all I want is backlight in a single color, white or clear blue or something.. With literally hundreds of possible configuration including per key customization, it is very easy to get lost trying to set up simple backlight that is not constantly blinking in all possible colors. I once set up the keyboard in some blinking craziness mode by hitting some keys by mistake, I had to go find the manual and it took me about half an hour to manage to get back to simple backlight without multicolored blinking.
Extra key-Caps are a nice bonus
The volume control rolling thingy is the best feature of the keyboard, works without any driver in Linux/Win/Mac.
So all and all it is pretty good, but could be better without wireless and without the hundreds of RGB settings and with a proper cable management thing, or at least a standard USB-c plug not at the bottom of a hole..
