Do you need a spare part? Is your product defective? 

Contact us directly! Our in-house RMA service offers immediate and fast help. We offer direct technical support, product repair or exchange - no matter where you purchased the product from. Only a few articles can still be handled by retailers. Of course, our support will inform you immediately in such a case.


We'd like the RMA process to flow as seamlessly as possible. The more accurate and detailed the information we receive from you, the faster your problem can be resolved.

Please provide the following information:

• Which product does this concern?

• Did the problem occur with other components, and if so, which?

• A detailed description of the problem

• Proof of purchase - if available
