FWIW, I also bought one of these on a discount close-out from Shopko. When I bought it I asked about warranty and they assured me that it was covered by the manufacturer’s warranty (1 year). It worked great for about 3 weeks, and I really liked it. I recharged it overnight Saturday night and come Sunday morning it wouldn’t turn on at all. I contacted Azpen and they said that they are NOT honoring the warranty on units purchased at Shopko, because Shopko is in bankruptcy, and has never paid them for the purchase of the units! They suggested I contact Shopko and of course Shopko says “too bad, so sad, no refunds”. So, I am going to have to dispute the charge on my credit card. What a pain in the BEHIND!
