@peggyn I found this FDA warning letter to them.

Peggy -- yes I know of a few people have used this and had some relief in their symptoms, and others who have tried it and didn't work for them. This is the frustrating part of neuropathy: our bodies are all different, and the way in which we came down with neuropathy is different (there are over 100 different ways) -- so therefore what works for one person, will not work for others -- we want so badly to find an answer to lessen our pain, that sometimes we are willing to spend many dollars to no avail -- I liked the comment that we need to find peace within us regarding our neuropathy,

@peggyn there is another older discussion started by @dutchman09 that you may want to read through which talks about the Rebuilder device.

My son's friend's friend bought it and said it helps tremendously, but I still did not buy it. I have bought so many things that do nothing, that I was still skeptical. It is expensive!
