I have idiopathic neuropathy in my feet. I tried the rebuilder and was even given an extension to their performance guarantee of 45 days. It never did anything for me so I returned it for my money back as stated in their website. Well lo and behold, they are appear to be broke and couldn't make good on the money back guarantee. So now they have the Rebuilder they sent me AND my money. They offered to send the Rebuilder back but that wouldn't do me any good. They seem to be sincere about wanting to return my money but who knows. I've been in business for a long time and can see the handwriting on the wall. I suspect they will close their doors soon unless some angel investor comes to their rescue.
