Read lots of reviews on this spa as had some questions on quality, reliability, performance. Was concerned about the 110V and pump/heater combo. Have had this installed now for two weeks and this spa has exceeded my expectations. No leaks in fittings, water temp at filling was 51 degrees and took 44 hours to heat up to 103 degrees and has held that since. First week of operation temps were 30-50 and it did not run much. Our daytime temps have been in 60's and 70's for last week and the spa barely runs except for 1x per hour self check and the 2 auto filter cycles. Jets are more than sufficient for massage and air bubbles, light and waterfall are nice touches. Built-in Ozonator is major plus. Temps do not fall during use, in fact I find with the pump running during use temp actually can increase a degree (remember pump is also the heater). Cover fits perfect and like I said is maintaining 103 degrees without running much. Seating for 5 is two bench seats for 2 average size adults and the lounge position. I usually use it alone so very spacious, 3 or 4 adults would be comfortable, but 5 is very doable. Last spa I owned was 20 years ago, was a high end 220v spa, all the bells and whistles ... would probably be a $12,000+ spa now (not including the 220V prep) ... this Lifesmart spa performs comparably in my opinion. I would recommend this spa to anyone.
