Really good keyboard only went with me the light is always on even when the PC was made.

The keyboard is really top handles and really hard. The writing feeling is really great. I had previously had a G19 and was with this here just so happy and I have the display a bit missing. The only problem was that the lighting of the keyboard has a night off always sporadic although the PC was made. Illumination turns whatsoever then if the PC is off and you press a button, and I even was able to observe in other keyboards this behavior. This seems to be normal and is also OK. But as I said this sporadic switch without an intervention was very annoying because the lighting is really bright. According to a statement from the really friendly Logitech support that's probably not normal behavior.
