Item malfunctioned during the 30 day returns period. (The customer should install and operate the item properly per the product manual instruction.)
Attention
For items that arrive damaged or are defective, the customer MUST provide videos or photos to support the claim that the item arrived damaged or is malfunctioning. If a customer refuses to or fails to provide videos or photos of a claimed malfunctioning/damaged item, this return will be treated as “buyer’s remorse” and the customer is solely responsible for shipping it back. Once we have received the approved returned item, we will review its condition. If the item is found to be defective, we will issue a refund within 3 working days.
