Product Warranty Policy

This policy applies to all electronics products sold by our company (operating an electronics business in the United States) and aims to clarify the scope, duration, and process of product warranties to protect users' legal rights and provide reliable after-sales support. If you have any questions, please contact our customer service at +86 19202338340. Customer service hours are Monday to Friday, from 9:00 AM to 6:00 PM (UTC+8:00).

1. Warranty Period

All electronics products provided by our company come with 1-year free warranty starting from the date you receive the product (the warranty period is based on the logistics receipt record, no extra registration is required, and the warranty activates automatically upon receipt).

Additional Note: Orders can be edited/changed within 12 hours after placing the order. If the product model changes, the warranty period will begin from the actual receipt date of the changed product. For in-stock orders, once payment is completed, the product will be shipped within 1-2 business days (excluding weekends and holidays), and the estimated delivery time is 5-7 business days. It is recommended to keep the receipt for warranty inquiries.

2. Warranty Coverage

If the product experiences any quality issues due to non-human factors during the warranty period, we will provide free repair or replacement of parts (subject to product inspection results):

• Product manufacturing defects that prevent the product from turning on or functioning correctly;

• Malfunctions in core components (e.g., motherboard, screen, power supply) due to non-human damage, affecting the normal operation of the product;

• Malfunctions occurring during normal use (proof of usage may be required).

3. Non-Warranty Coverage

The following situations are not covered under the free warranty. If repairs are required, we will charge for repair and replacement parts:

• Human damage: Including, but not limited to, dropping, collision, squeezing, water damage, unauthorized disassembly, modifications, or improper use leading to faults;

• Force majeure: Damage caused by natural disasters, fire, lightning, and other external factors;

• Cosmetic damage: Scratches, dents, and other non-functional damages that do not affect the normal use of the product;

• Products that are past the warranty period;

• Products without valid proof of receipt or unable to prove that they were purchased from our company;

• Normal wear and tear of accessories (such as chargers, data cables, etc.).

4. Warranty Process

If your product has an issue within the warranty period that falls within the warranty scope, please follow these steps to apply for warranty service:

1. Request Repair: Please contact our customer service team promptly after discovering the issue (phone: +86 19202338340), provide the product model, fault description, logistics receipt proof, and product fault photos/videos.

2. Fault Verification: Once we receive the repair request, customer service will contact you within 1-2 business days to verify the fault and determine if it meets the warranty conditions.

3. Product Return: If the fault is covered under the warranty, customer service will provide you with the return address and instructions. Please pack the product securely and return it (return shipping fees are initially borne by you, but we will cover return shipping after repairs).

4. Inspection and Repair: After receiving the returned product, we will complete the inspection and repair within 3-5 business days (complex faults may take longer, and customer service will notify you in advance).

5. Product Return: Once repairs are complete, we will ship the product back to you within 1-2 business days, and the estimated delivery time is 5-7 business days. You can contact customer service for the tracking number.

5. Special Notes

1. Warranty services only cover product quality issues and do not include value-added services such as data recovery or product cleaning.

2. If, during the repair process, we determine that the fault falls outside the warranty coverage, we will notify you and provide a repair quote. You may choose to proceed with paid repairs. If you choose not to repair, the product will be returned to you, and return shipping costs will be borne by you.

3. If the product cannot be used normally after two repairs during the warranty period, we will replace it with the same model. If the same model is not available, we will offer a product of equal value or a refund, subject to customer service communication.

4. Please keep the product and related accessories in good condition. Missing parts during the warranty process may delay the repair.
