Q: What about quality assurance?
A: We offer one warrantee period beginning from the time of shipment for OEM application, we can provide spare parts for replacements, if our serious product problems, we can make replacement of free charge. But if the product is damaged due to rough handling during the transportation or incorrect usage, we are free of any responsibility, but we will still provide help to the buyer issue resolved, thus all the spare parts or expenses should be borne by buyer.
