How to deal with the failure?

first of all, if there are problems with our products, we will provide free maintenance service for 2 years.

Secondly, if the error is caused by improper operation, the customer will pay extra fees. Within 2 years, the customer only needs to pay for materials and bills. Customers only need to pay for materials and labor costs in 3 years!

Three, the warranty time can reach 5 years, we can provide customers with the same material of the new product (if there is), but the buyer needs to pay the cost!
