No packages will be accepted without the RMA document clearly marked on the outside of the package. After inspecting and testing, we will return your product, or its replacement using the same shipping method used to ship the product to Decode within 30 days. In your package, please include your contact telephone number and a brief explanation of the problem. All returns must comply with our Terms and Conditions.
