The hot tub itself is 5 star. I ordered this hot tub May 15 and it just came 5 months later. That’s the reason I’m giving it less stars. The jets are strong and don’t let only 19 fool you it’s enough to get the job done. It did take a full 30 hours to get to the temperature of 100 so hopefully it will hold. When you are in it it looses about a degree every 10 minutes. It is a quality hot tub for the money. Other then the ridiculous delivery issues which wayfair didn’t do anything about I would it’s a great buy.
