I bought my unit a a wholesale club store in the late part of spring 2019; needless to say the price was very attractive and the club has a great return policy. (Just in case, right?) It's beginning of November of 2019, I can comfortably report that I was very happy to get a great deal and did not have to even think about the generous return policy.  It's not that loud, my energy bill was not through the roof, and I used the unit consistently throughout the summer.
