Wow!!! Talk about "the works"! This spa has it all. We wanted a larger tub for both socializing, as well as the variety of seating. We received the tub in June of 2004. Since then, we've used it pretty much every day. We tested a whole bunch of other tubs, but after looking at all the benefits that the Vita offered, it was a no brainer. This particular model has the Symphonic Wave Seat, which gives a great back massage. It also has the stereo and fiber optic lights. I haven't had any problems yet, so I can't answer how it would be resolved. I just want to close by saying that if you're looking for a spa, be sure to include Vita in your search. We love it, our friends love it, and we know that we made a great choice!
