I play on this keyboard, absolutely normal software on it (Key Dominator). Installed, clicked to load backlight profiles into the keyboard memory, closed the program and have not turned it on for several months. And the backlight works independently. So I don’t understand all the claims about the keyominator’s crookedness, do people adjust the backlight all day long? I'm not particularly demanding and in my opinion for my money it's a very worthy Claudia.
