Bests & Worsts Reviews from Amazon

I had a problem with this unit not turning off automatically (not sure why) resulting it running continuously unless manually switched off. The result was a shocking electric bill. When I contacted Amazon within the 90-day window to process a return, they informed me that because it came from a third-party seller (Woot), only Woot's 30-day return policy would be honored. No where on the item description page is this communicated. BE AWARE!!!
