Dear Users:
Thank you for choosing our products. To protect your legitimate rights and interests, we have formulated this After-sales Service Description (“this Description”) in accordance with national laws, regulations and industry standards. This Description applies to all products purchased through our official authorized channels.
One-year free warranty service is provided from the date the product passes acceptance.
The warranty period starts from the date of product acceptance. If the customer cannot provide a valid acceptance certificate, the warranty period starts from the factory date corresponding to the product serial number.
During the warranty period, if the product fails under normal use (e.g., the card cannot be recognized at startup, abnormal firmware information, etc.), and our inspection confirms it as a quality defect of the product itself, free warranty service will be provided.
The product operates under the rated temperature and humidity, power supply standards, working conditions and other environmental conditions specified in the manual, with compliant supporting software and hardware, and without unauthorized modification or over-limit use.
If a faulty product within the warranty period is confirmed unrepairable after our inspection, we will provide a replacement of the same model and specification. The replacement device inherits the remaining warranty period of the original product. If the same model is discontinued and out of stock, both parties will negotiate to provide an alternative model of equivalent performance.
The product is not eligible for free warranty service under any of the following circumstances:
The product is out of the warranty period, or was purchased through channels not authorized by us.
The product serial number label is missing, damaged or altered, or the serial number does not match the product itself.
Man-made damage: including but not limited to damage caused by unauthorized disassembly, modification or repair.
Physical damage caused by external force: physical damage caused by accidents, falls, impacts, etc.
Damage caused by harsh environmental factors: damage caused by flooding, fire, lightning, high temperature, oxidation, corrosion, liquid ingress, etc.
Faults caused by use under abnormal working conditions such as temperature, humidity, voltage or current beyond the limits allowed by the product specifications.
We reserve the right to revise and improve this Description according to actual circumstances. The revised Description (“Updated Description”) will be notified by our staff via email, official website notice or other forms.
Products sold on or after the effective date of the Updated Description will be subject to the Updated Description. Products sold before the effective date of the Updated Description will still be subject to the Description in effect at the time of purchase.
For products beyond the warranty period or ineligible for warranty service under our warranty terms, we will perform paid repairs at standard rates after notifying the customer and obtaining their consent.
For free repairs within the warranty period, round-trip logistics costs shall be negotiated and agreed by both parties; logistics and inspection costs arising from paid repairs shall be borne by the customer.
The repair cycle for common faults is 10-15 working days after receiving the returned product. For complex faults, the estimated time will be communicated to the customer in advance.
Please contact after-sales staff to obtain the official repair address. Do not send products to unauthorized locations on your own.
