This little Jetsetter spa gets used one a day or more my myself and my husband. We both work out regularly and he trails runs most days. Those massaging jets on the spa are wonderful after our exorcise. We want it clean and ready to go at any moment, and Silk Balance eases the maintenance to about as simple as possible. The additional plus of emerging without the feel of a chemical bath that dries and wrinkles the skin is what keeps us using Silk Balance. –Linda Bilyeu Bend, OR
