Return and Refund Policy

Unless otherwise required by applicable law, all sales are final. We do not accept returns or exchanges for change of mind, software or operating system compatibility, performance expectations, or other non-defect-related reasons.

Defective Products

If you believe a product you received is defective, please contact us promptly with a description of the problem and any information reasonably necessary to diagnose the issue. This may include photographs, video, error messages, system logs, or the results of troubleshooting steps we provide.

If we determine that the product is defective, we may, at our discretion and as appropriate to the circumstances:

• Repair the product;

• Replace the product with the same or an equivalent product; or

• Issue a refund.

We may require the product to be returned for inspection before determining whether it is defective.

Compatibility

Customers are responsible for determining whether a product is suitable for their intended use before purchasing.

Incompatibility with a particular operating system, software package, peripheral, expansion card, component, or other hardware does not constitute a product defect unless the product fails to meet compatibility or functionality specifically represented by us.

Products based on alternative processor architectures, including LoongArch, may have substantially different operating system, software, driver, and peripheral support from conventional x86 systems. Purchasing such a product does not guarantee compatibility with software or hardware designed for other architectures.

Physical Damage and Modification

Products damaged through misuse, improper installation, electrical damage, unauthorized modification, overclocking, physical damage, or use outside the manufacturer's specifications are not considered defective for purposes of this policy.

Modification of firmware or installation of alternative operating systems does not by itself void eligibility for a defective-product claim. However, problems caused by such modifications or software are not considered product defects.

Shipping Damage

If a product arrives physically damaged, please contact us as soon as reasonably possible and retain the product, packaging, and shipping materials. Photographs of the product and packaging may be required so that we can evaluate the damage and, where applicable, pursue a claim with the carrier.

Return Authorization

Do not return a product without contacting us first. Unauthorized returns may be refused.

If a return is authorized, we will provide return instructions. Products should be returned with all included components and accessories unless we instruct otherwise.

Nothing in this policy limits any rights or remedies that cannot legally be excluded or limited under applicable law.
