A: Please stop using it immediately and keep the on-site evidence. Contact customer service within 24 hours, and we will arrange an engineer to review the load data on site. If it is indeed a quality problem, we promise to "refund one and compensate one" and bear the transportation costs.

A: It is recommended to test the resistance value every 6 months (the company provides free testing tools). When the resistance value deviation exceeds the initial value ±15%, it needs to be replaced as a whole.

A: The company has 12 overseas warehouses around the world, providing "localized after-sales": 48-hour response mechanism, global allocation of spare parts, and engineer video guidance for maintenance.
