Thats part of the problem these were sold no return they were sealed units. So not really on the seller. Kind of dissapointed that documentation states lifetime warranty but call them and they cant help. If a company goes out of business thats one thing but for a company to put Lifetime on their warranties and then not keep parts or honor it. Is horrible. Reciept in hand may have been discontinued but it is a brand new purchase and should be honored.
