“Somewhat skeptical and wasn't expecting too much when I bought the SaunaMAX Pro to use in our new sauna. As a 72 year old senior with back problems, I was willing to try almost anything that might reduce my pain and stiffness from an automobile accident a number of years ago. The results were almost instantly noticeable. The relief from the pain and stiffness has me using it first thing in the morning, and again right before bedtime. Even our senior cat loves it, and is running around like a kitten again. May even look at a second unit in the future. LOVE IT !”
