Return and Refund Policy

• If the product is still within the return period defined by the platform on which it was purchased (e.g., Amazon.com 30-Day Return Policy), we will follow the return and refund policy of that platform.

• If the product exceeds the return period of the purchase platform, we offer return and refund services for products that are still under warranty.

Return and Refund Procedure

1. If you wish to request a return and refund, please contact us at support@yeismooi.com and provide the following information:
   1. Order number and purchase platform
   2. The serial number (S/N or SN) of the defective product (usually found on the product label)
   3. Reason for return
   4. Video/photo evidence
   5. Please ensure your explanation and media files clearly show the issue. We reserve the right to request additional video evidence of the issue encountered during troubleshooting.

2. In some cases, it may be necessary to return the product for quality inspection. The buyer must ship the product back to us and provide a valid tracking number.
   1. If the wrong product is returned, the defective product is not returned, or an unauthorized return is made, the warranty for the product will be void.
   2. We are not responsible for any data loss during transportation or for any personal items included in the return shipment, regardless of whether the loss occurred intentionally or unintentionally.
   3. The buyer is responsible for any damage or loss incurred during shipping. We do not provide refunds for items damaged in transit.
3. Once the refund eligibility is confirmed—or, in cases requiring a return, once we receive and confirm the returned product—we will process your refund within 10–15 business days.
4. Refund Amount = Actual Cash Paid for the Product in the Order × (Remaining Warranty Period ÷ Total Warranty Period)
