The Rosewill RK-9000 v2 RGB is one of many similar styles of keyboard, one thing that sets this one apart is the Cherry MX Switches. Most keyboards with hardware controlled LEDs and Macros tend to favor a cheaper switch to be able to keep costs down. Rosewill decided that they wanted to ensure that they use the best switch while still giving users a full set of hardware controlled options, a bold move for sure.
In terms of comfort, usability and design, there are certainly very few complaints, in fact, only one; the right angle connector. This is a pet hate of mine as I change where my computer is placed quite often. When it is on the side the 90° connector faces, then the cable is great, when it is the opposite way, I have to swap the cable as it annoys me too much, if it was straight, it wouldn't matter.
Overall, the keyboard is quite unremarkable, which isn't a bad thing, it is perfectly fine. It just doesn't really do anything more than the other options that are available. Having said that, if you are in the market for a keyboard that has RGB functions, macro functions, media functions and more, then I would recommend this with no problems. The switches alone do give it somewhat more of an edge.
