Online return or refund request form

Terms and Conditions

In the event that your MOS product does not meet your needs, our refund policy allows you to return the product within 30 days of the purchase date. To qualify for a refund, the product must be unused and in new condition in its original packaging. Proof of purchase must also be presented for all return and refund requests.

Return and refund requests will only be processed by MOS for purchases made through our website at or through our sales team. For the purchases of MOS products from authorized retailers, please contact the retailer’s customer service department directly for their return policy.

Always contact the retailer where you purchased your MOS products before returning them. Products returned without prior request will not be accepted. Returns after 30 days from the date of purchase will not be accepted. MOS reserves the right to refuse returns that do not comply with the terms and conditions outlined in our User Guide and Warranty policy. Please note that shipping costs are not refunded by MOS.

Return procedures

For products purchased from an authorized MOS retailer, contact the retailer’s customer service department directly for the return procedure. For products purchased directly from MOS, follow these steps:

  • Clean the product and put it back in its original packaging.
  • Include a copy of proof of purchase (invoice or delivery slip) in the return box.
