I don't have any firsthand info about the rebuilder, but I happened to have a chat with a fellow this.... er.... yesterday afternoon, so I thought I'd pass it along.

The gentleman was a very spry 78 years old, (appeared early/mid 60s) and said he's had PN for about 3-4 years in his right foot, and now beginning in his left. He said he bought a rebuilder for ~$400 some years back (and that he thinks many insurance companies will pay for it now w/ doctor's prescription (?) ). He believes it beneficial - for symptoms anyway, which may be enough for some of us; said it eliminated the shocks/pricking pains, and temporarily (for a few hours after use) lessened his other PN symptoms when used daily. He recommended it highly to me.

OTOH, while helping his symptoms, his PN overall hasn't really reversed, and as noted, is now manifesting in his other foot.

FWIW - secondhand hearsay.
