How to File a Warranty Claim
Email support@bymyth.com with the subject line "Warranty Claim — [Order Number]." Describe the issue and include a short video or photo demonstrating the problem if possible. We respond within one business day. If the claim is valid, we ship a replacement before you return the defective unit so you have zero measurement gap. A prepaid return label is included with the replacement shipment for the defective device.
Zero measurement gap commitment: for valid hardware failures, we ship your replacement before requiring the defective unit back. You do not lose a single training session waiting for a replacement.
