I set up the hot tub with no problems.  There were several reviews about the door being hard to screw back on, but it was no big deal.  It heated the water up in just about the same amount of time as described.  I got in for the first time tonight and loved it.  I like that the led light has several colors to pick from.  A lot of reviews said that the waterfall was too loud.  If you turn it all the way up, it is loud, but you don’t have to turn it on high.  It’s not too loud when turned lower..
