Very poor customer service, their website claims “Most parts offered by USP come with a warranty against manufacturer defect or failure for a period of one year from the date of purchase.”, however getting them to honor their warranty on defective parts is basically impossible. First they ask for pictures, then they send a form for you to fill out giving you the impression their willing to work with you. Next they deny the claim without contacting you. It’s only after about two weeks go by you end up contacting them for a status update only to find out they refuse to honor their own warranty. No wonder their BBB rating is an “F”! – Do not buy anything from this company unless you are sure it won’t fail due to defect.
