I got my Polar Dive 4 months ago and it has been life changing. As an above the knee amputee and recently diagnosed with rheumatoid arthritis, I wanted to try something different and remain off medication. THIS WORKS!!!! I start ever day with a plunge and sometimes numerous times daily. When I travel I just don't feel as good and It's because of my Polar Plunge. I recently had a minor issue and they told me how to fix it immediately and in 3 minutes I was up and running again. The customer service is excellent. I highly recommend this product, you will not regret it.
