No clue, as again they were one of the listed Authorized Resellers. Someone from right here on this list:
https://www.furmanpower.com/connect/where-buy I'm not going to out the store and I never brought it up when it happened a few months ago, but it was a pain to deal with 2 bad units in a row. The units were all still sealed in the box, with plastic wrap on the units, the cords were tied with plastic caps on the plug, and nothing about the units said they were used or opened. If they were used, they did a heck of a job hiding it.
Not sure why you are defending the brand so staunchly, and I even said maybe I just got really unlucky, but the experience turned me off of the brand for a 3rd try. If you work there or something and want to contact me in an official capacity for more information, I'll be happy to share, but I'm not going to trash the store in question since I have no reason to believe they were not new units as advertised. I'm not telling anyone else not to buy them, but sharing information I learned about some competitors because of the experience. YMMV. Regards.
