We have moved three times over the past 10 years and each time the hot tub has stayed with the house. I have shopped for and purchased a new tub with each new house. In each case I have returned to the Sundance Optima. It is an excellent spa with great reliability. We have not had any issues with three purchases of this spa. The spa has gotten better over the years with the ozone system, waterfall, and lighting. We love the foot jets. This is one of the only spas I have sampled (and I have sampled a lot with each new purchase) that fits my small wife without floating her out of the seats, yet has seats deep enough for me at 6'3". I am proof that someone would buy this spa over and over again :
