“The only bad thing is that the software is pretty hard to found, I don’t even know if it’s out there actually, anyways the product fantastic, the switches are smooth and lubed and the quality of the product is excellent”
“Good switches, nice keycaps. Shitty outsated driver. Some rgb doesn’t change even when using its own setting, doesn’t work with signalRGB. Sometimes when I turn on my pc the keyboard glitches and i have to switch to and from wireless mode for it to work…”
