--in reports about the Rebuilder over the years may stem from the fact that its design has been tweaked at least several times, partly due to company having undergone reorganization on at least one occasion. It's my understanding (through contacts at the Neuropathy Association and some first hand reports of users) that the people who originally developed it no longer have the exclusive rights to it, and that there have been some contentious battles over the years over that group and other groups' rights to produce/market the "original Rebuilder" versus similar copycat devices.
