It's marketing hype..
I so wanted to love this product. Been dealing with back issues and wanted some relief over past year. Saw this in my chiro office and said let me give it a try. Waste of time and money. This isn't it. It's overpriced and doesn't do what it says. It lacks power to fully do the job. I'm dealing with ongoing issues in the lower back (s1). It is an average product, just a lot of marketing hype. IT SHOULD BE AROUND 199 INSEAD OF 600
