Came earlier than was scheduled, so didn't have the site prepared, so can't give a total review of how it works until we get it set up. The people who delivered it were very nice. Can't wait to get it all set up.  so only giving it 4 stars right now. 2/8/2021 Update: Got everything up and going and I am loving this Aquarest hot tub. Working great, keeping the water 102 even with outside temp in the 30's.
