UPDATE:
What I have discovered by accident sometimes. This keyboard is basically a "Choc Noppoo Mid". So Lioncast takes its name draufgehauen, few LEDs reingehauen etc. and passes it on to the customer at a good price also. and of course with EN layout. I think the "Choc Noppoo Mid" does not exist with DE Layout. I want to not judging or condemning. The make sure other manufacturers also. And that there is a "Noppoo" is can not be bad, because these keyboards are generally considered to be good on the net in various forums.
Here's a screenshot to: [...]
So you make here certainly nothing wrong with the keyboard, especially when you consider that it is probably a "Noppoo".
