I've had this product for almost 2 months now.  My wife has knee problems, and I have a severe back problem.  We've had 3 portable Jacuzzis before, all inflatable and died within a season or 2.  They couldn't be used during the winter.  After we got back from vacation where there was a Jacuzzi in the room, we decided to get another.  We rolled this unit into the fenced back yard and plugged it in (fits through a standard 1 door chain link gate with no problems). There is no comparison. Even with Father in-law's 6 person giant Jacuzzi.  This beats them all.  Very quite operation, knee and back problems disappear for hours.  Getting a better night's sleep now too.  1 extra strange benefit, my winter psoriasis seems to be almost gone now as well.  Maintains heat very well (104) when below freezing.  Electric bill only up by about $20-$25.   The folks at Wayfair had the BEST price and BEST service people, bent over backwards to answer my questions and help.   If your waffling, GET IT!
