Warranty Policy

YIshengcai provides a one-year limited warranty against manufacturing defects, in addition to rights that cannot be excluded under applicable consumer law.

1. Warranty period

The limited warranty lasts for 12 months from the recorded delivery date for the original purchaser. A replacement or repaired product is covered for the remainder of the original warranty period or any longer period required by law.

2. What is covered

The warranty covers verified defects in materials or workmanship arising during normal use and in accordance with the product instructions. Depending on the issue, we may provide troubleshooting, repair, replacement with the same or functionally equivalent product, or a refund where appropriate.

3. What is not covered

• normal wear and cosmetic changes, including scratches, coating wear, strap ageing, or battery capacity reduction expected over time;
• accident, impact, crushing, fire, extreme temperature, misuse, neglect, improper storage, or use contrary to instructions;
• water or moisture damage where the product is not rated for that exposure, the seal has been compromised, or operating instructions were not followed;
• damage caused by an incompatible charger, power source, accessory, software, or third-party service;
• unauthorized opening, modification, repair, parts replacement, or altered/removed serial numbers;
• loss, theft, or data loss; and
• products purchased from an unauthorized seller or without reliable proof of purchase.

4. Making a claim

Email support@yi-shengcai.com with your order number, product model, serial number if available, a description of the problem, troubleshooting already attempted, and clear photos or video. Do not send the product until we provide authorization and instructions.

5. Assessment and remedy

We may ask you to complete reasonable troubleshooting, update software, reset the device, or return it for inspection. Before sending a smart device, back up anything you need, remove personal information, unpair accounts, and reset it where possible. We are not responsible for data loss during warranty service to the extent permitted by law.

If a covered defect is confirmed, we will provide a reasonable remedy and cover approved shipping costs required for that remedy. If inspection shows the issue is outside warranty, we will explain the result and may offer a paid solution where available. No paid work will be performed without your agreement.

6. Replacement products

A replacement may be new or professionally refurbished and may differ in color or minor appearance when the original model is unavailable, but it will be functionally equivalent or better. Replaced parts or products may become our property where permitted by law.

7. Legal rights

This limited warranty does not exclude, restrict, or replace statutory guarantees or remedies that cannot be waived. Any limitation applies only to the extent permitted by applicable law.
