I'm very pleased after using the Aero Spa. Not only is the Aero Spa worry free. I don't have the expense of chemicals. It's also much more pleasurable because I don't smell the chemicals. I feel your product is a great value and it will pay for itself in a short time not having to buy chemicals. My cousin just installed a new hot tub and I recommended the Areo Spa to him.
Sincerely, Greg Holt
