Return & Refund Policy

1. Policy Overview

This Return & Refund Policy explains our voluntary return process for eligible orders. It operates in addition to mandatory consumer rights that cannot lawfully be excluded.

Because smart eyewear contains electronic components, returns may require condition checks, included accessories and reasonable evidence where a defect or delivery problem is reported.

2. Cancellation Before Processing

A cancellation may be requested within 12 hours after payment if processing, packing or shipment preparation has not already begun.

Send the request promptly to doublezip@126.com with the order number. Cancellation is not guaranteed after operational processing starts.

3. Standard Return Request Period

Eligible standard return requests should generally be submitted within 7 days after confirmed delivery.

Submitting the request within the period does not automatically mean every item qualifies; product condition and the other requirements below also apply.

4. Standard Return Eligibility

5. Reasonable Inspection vs. Extended Use

Customers may reasonably inspect a product after delivery. Extensive use, physical damage, modification or condition changes that materially affect the product may reduce or remove eligibility for a voluntary return.

6. Damaged on Arrival

If the parcel or product arrives damaged, contact us within 7 days. Keep the shipping packaging and provide the order number, photographs of the outer package, shipping label, product and video where useful.

7. Defective Product

If a product appears to have a manufacturing defect, contact us with the order number, model, description of the problem and supporting evidence.

We may perform reasonable troubleshooting before deciding whether a physical return is necessary.

8. Wrong Product or Missing Components

If you receive the wrong model, color, quantity or a package is missing a required included component, contact us within 7 days and provide photographs of the product, packaging and shipping label.

9. Return Authorization

10. Return Shipping Costs

Where the Problem Is Our Responsibility

If a wrong item, covered defect or pre-delivery damage is confirmed as our responsibility, we may cover reasonable return shipping or offer another appropriate remedy.

Preference-Based Return

For an approved return not caused by our error, the customer is generally responsible for return shipping unless applicable law requires otherwise.

11. Return Packaging

Smart eyewear should be packaged securely to reduce transit damage. Where available, include the protective case, charging accessory, manuals, included components and original retail packaging.

12. Return Inspection

Returned products may be inspected for product identity, physical condition, included accessories, customer-caused damage, unauthorized modification and consistency with the stated return reason.

13. Refund Method

After an eligible return is received and approved, refunds are normally issued to the original payment method used for the order.

Customers should not be asked to provide unrelated payment credentials in order to receive an ordinary refund.

14. Refund Posting Time

After we issue an approved refund, the customer's bank, card issuer or payment provider may require additional business days to post the credit.

15. Partial Refund or Replacement

Where appropriate and agreed, a minor issue may be resolved through a partial refund if the customer chooses to keep the product. A replacement may also be offered where appropriate and inventory is available.

16. Incorrect Address, Refused or Unclaimed Delivery

Customers are responsible for accurate delivery information and for responding to legitimate carrier or customs requests.

Where a valid shipment is returned because of an incorrect customer-provided address, refusal or failure to claim the parcel, reshipping or refund arrangements may be affected by unrecoverable carrier costs, subject to applicable law.

17. Customs & Import Charges

Refusing a shipment solely because of legitimate destination-country customs, VAT or import charges does not automatically create a right to a full refund.

18. Payment Disputes

Customers may contact us directly so that we can review order records, tracking, product evidence, refund status or warranty information and consider an appropriate resolution.

This policy does not remove rights available under applicable law or through the customer's payment provider.
