I received this hot tub around 2 1/2 weeks after ordering, not too bad delivery time. I wired a dedicated outlet on the patio, filled the tub and then turned it on. Pump started making this horrendous noise. I turned the tub off and unplugged it, having to wait until the next day to call the manufacturer. They told me they had received a batch of bad pumps. They would have replacement pumps in stock between 1 week and 1 month. WHAT? They did send me the new pump arriving in about 10 days from the day I first called. Installed the new pump without much fuss. Now working wonderfully and correctly. I would hope the fixed the pump problem before they ship the next batch of hot tubs out! Works perfect, would be a tight fight with 4 adults but it is a fair price and a good working piece of relaxation equipment!  

Pros: Easy install plug and play
Cons: small size if going to try to fit 4 adults
