Please provide photos and videos of damage or quality issues within 7 days after receipt. After verification, we will provide: free replacement of the corresponding quantity, price discount (deduction based on the defective ratio), or return (only for serious bulk quality problems, shipping fees to be negotiated by both parties).

Non-artificial damages during the warranty period will be provided with free repair parts.

Chinese and English installation manuals and video tutorials are provided free of charge. If required, we can arrange technicians for on-site guidance (fees to be charged separately, including travel and service fees). We can also assist with remote troubleshooting via video conference.
