I have the exact Power EP 15A and had a issue. I called and no service unless I wanted to pay $$$$$$$ for them to trouble shoot. I had my plant electrician check it out and it was a 5.00 part needed that he picked up from a electrical supply. I would not think twice on buying another. If you really look inside there is little that can go wrong that cannot be serviced locally to my knowledge.
