Detailed Answer
LIDER 2-year trade-in process: 1. Call customer service to confirm trade-in eligibility (serial number + purchase proof); 2. Ship back the old unit (or go through a regional service point); 3. Inspection and confirmation (non-human damage); 4. Receive a new unit of the same model. Note: trade-in scope, fees, and lead time are subject to the contract.
