Very solid keyboard. Has some heft to it. Easy to install switches and keys. Knob is a huge value add for me. LEDs are pretty good. Software included is pretty easy to use once you get over the small learning curve. Keydous's documentation is great for getting started in the software.
The keyboard sounds and feels great to use. The build feels solid. The LEDs are very bright and the RGB functionality is fairly standard. The case is plastic but the plate is steel.
I used this as the base for my second keyboard using the holy x panda switches with the dwarvish keycaps. color and rgb are real nice as well as the installation was super simple and easy. one downside is that the f keys are kinda snug so if you mess up with installing the switches it could be difficult to remove them and reinstall them.
Stabs came in in a decent state, it's easy to set up and works fine. Wish it had VIA/QMK support, but it's good enough in it's current state, good as an intro board.
The reason I bought this keyboard was specifically to use the bluetooth and 2.4 functions. Neither of these functions have worked since I took it out of the box. It is just the fourth wired keyboard I have now, and it frequently enters pairing mode even though it will not pair to anything despite being wired.
