I recently purchased a Master Spa Legend Series and find chemical maintenance to be a breeze. It goes excellent with a steam sauna I have had for almost 20 years and still use numerous times/week. Now I have spa days. I lay in the sauna, take a cool shower and then jump in the hot tub. Feels so good, my body is totally relaxed and I have never slept so sound. For me, purchasing the hydrotherapy spa was worth holding off on buying a new pin.
