Please don't get wrapped up in the expensive packaging and fancy trimmings of the $500+ machines. I hate to see people get ripped off. Make your own footplates or buy indian in the machines footplates. Mine that I bought from him work really awesome. I would have been so upset to have bought one of the expensive ones just to have it break or not work. With indian in the machine's they are going to work because they are just metal plates, then you hook up a battery charger that I found on amazon.com for only $12. And voila, you see the current bubbling in the water, magic. I am very grateful for what this technology did for me. It really helped me regain my health and get out the mercury. For those who are still questioning, give it a try at a local practitioners office and you will be a believer. When they go to dump out the bucket, follow them to the bathroom and watch what comes out at the bottom of the bucket, see all the black particulates that have been holed up in your body clogging it. Then watch as this load decreases with each bath you do. Best to you!
