Detailed Answer
LIDER's core after-sales commitments: 2-year trade-in (replace an old unit with a new one within the warranty period), national technical support hotline, shipping of consumable parts, and rapid fault response (same-day reply). Service system: 400 hotline + regional service points. Non-human-caused faults are handled free of charge during the warranty. Confirm the trade-in terms (conditions/fees) when purchasing.
