YTMAG does not manufacture the parts, they are simply distributing them. They simply contract with a parts distributor and sell whatever they stock. Distributors too only sell product, as the parts are almost always manufactured overseas nowadays. That being said, when issues arise, as they seem to a lot lately with a few brands, then they should be made aware as the company/supplier will not do anything unless made aware thru complaints.
