I bought this spa with the Ozonator feature it was a waste of money it does not help with anything at all. The spa also has a motor and pump that start to have leaking problems after about 2 years ,if you get one I would live close by the dealer. The jets pop out and break after about 1 year and they are very expensive. The one good thing I can say about the spa is that it was not bad on the electric bill. If you are thinking about a spa I would recommend looking into one that you can get parts for at a variety of place's and not letting them talk you into the ozonator.
