I originally bought the GK61X kit from epomaker and not only did the RGB really suck but I could never get the software to work which was the main reason for the purchase. The RK68's RGB is much brighter and there are many more options. I haven't tried this software yet, but I probably won't need it since it has a 65 percent layout and I don't have to do much remapping. If you're not worried about RGB or software at all, it's still a really good choice. High quality keycaps, high quality frame. The thing is now even 5-pin hot-swappable. I checked the scan speed and it's around 250Hz. The support team told me the polling rate is 1000Hz. This should give you around 6ms of latency when using this board. Looks less cheap than the Epomaker board, even with the RK logo on the front. I plan to change this and will update my review if my mind changes.
