Due to the presence of visually similar products on the market, a proof of purchase is required when requesting warranty service. For large products, the product serial number must also be provided (all large Greenlife items have unique serial numbers to ensure better service). Shipping costs during warranty service must be covered by both parties — each party is responsible for the shipping fee to send the product to the other. If the product is out of warranty, the buyer is responsible for the shipping cost. For products purchased online, or orders where the delivery address is more than 20 kilometers from any of our branches, we only provide replacement parts (not in-home repair services) during the warranty period.
