We bought this spa for hydrotherapy for my arthritis. The after-effects are amazing! It not only helps ease the pain of arthritis while you're basking in the warm waters, but the heat has a lasting effect and I sleep like a baby! I keep it on a covered screen porch so I'm not bothered by weather elements or bugs. I've owned this for 7 years and it still works perfectly. Love the ozonating sanitizing feature. Saves us lots of $$ on chemicals every year. I have sensitive skin and can't stand the clorine in regular spas. We are moving to Arizona and can't take this with us, or we would! LOVE IT!!
