Unfortunately, we cannot offer the CH version at the moment. As soon as our suppliers have it, we will be happy to include it.

Antwort seitens Steelseries auf die Frage, ob/wann es ein CH-Layout geben wird:
"Thank you for reaching out to us. The planned release for the other layouts should be by the end of the month. "

^^' use the keyboard with Win CH -> What is the problem?
