We have had the Aero-Spa for almost 1 year and what a wonderful experience. We live in Wisconsin and all through the winter with the snow we did not have to go out and put chemicals in the hot tub. The hot tub was always fresh, no harsh chemicals on my skin and no not being able to use the hot tub due to inbalance of chemicals.

Love the product. A must have for all hot tub owners! info@aero-spa.net
