To open a support ticket for hardware related issues* (or to initiate an RMA request) for products purchased at VKBcontrollers.com, log into to your “My Account” dashboard, click “Orders”, and then click “Get Help” (see screenshot below as reference).
*For software, firmware, or button-assignment issues and questions, please use the official VKB Support forums instead (VKB developers and engineers are able to help).
Important: For VKB products purchased at third-party retailers (e.g., Amazon, X-plane, Dix30 Simulations, etc), you will have to contact their respective after-sale support team instead!
