The Eurotherapy Classic carries a comprehensive warranty, the length of which is covered on your invoice. This covers both electrical and mechanical faults in materials and assembly. Evidence of misuse, or repairs or modifications carried out by unauthorised third parties will invalidate the warranty. Normal wear and tear and any usage outside of that intended will fall outside of the warranty. Please keep your invoice safely as this will act as proof of purchase and validate your warranty. In order to assert a claim under the warranty, please send the complete device to the authorised service address, together with the invoice.
