After-Sales Information

Domestic After-Sales Terms (Mainland China)

The following warranty, replacement, and shipping terms apply only to customers in mainland China.

• These terms apply exclusively to products manufactured by ROBOSN, including those sold through authorized distributors.

• The warranty period we provide is 12 months from the date of initial acceptance after delivery. We are responsible for repairing faults not caused by the user (consumables are not covered under warranty). For issues arising from software modifications during product use, we may provide online voice/video guidance depending on problem complexity.

• Repair requests require submission of proof of purchase, a warranty card, or transaction records.

• Within seven days of purchase, if a quality issue occurs under normal use and the product has no exterior damage, present the warranty card or proof of purchase through official AMOVLAB sales channels or authorized distributors to arrange a free replacement with the same model. The distributor must immediately notify ROBOSN upon receiving the product to be replaced so that the replacement can be recorded.

• For products with user-caused damage, modifications, disassembly, or that are beyond the one-year free warranty period, the user bears round-trip shipping and repair costs. Fee structure: labor + parts.

• To ensure that your rights and interests are protected and that we can provide timely and effective service, complete the warranty card in full and obtain proof of purchase when buying AMOVLAB products.

International After-Sales Service

Warranty and after-sales arrangements for customers outside mainland China differ because cross-border shipping, customs clearance, and import/export requirements may apply.

• Spare-parts planning for international orders: Before shipment, ROBOSN evaluates wear-prone and vulnerable parts and may produce and include extra units as spares. We take particular care with aircraft-specific components because, unlike standard, widely available items such as propellers, they cannot be readily sourced or replaced. This advance planning helps anticipate most spare-parts needs before delivery.

• Replacement parts: If a part is damaged, ROBOSN can provide certain replacement parts. The customer is responsible for shipping costs.

• Return-to-factory repair: If an aircraft must be returned to ROBOSN, we can repair it and ship it back. However, cross-border returns are usually complicated by import/export customs clearance and related procedures. Therefore, we generally do not recommend return-to-factory repair for international customers.

• Remote support: We can provide remote guidance, including video support, or provide repair documentation.
