Mine has never moved that I could discern, but Rrae on here had a lead which moved all of the way down her back. That one was finally removed because it was not helping anyway.

Tchr012 had a generator which moved I believe, and ultimately the whole affair was switched out to another unit much to her joy.

Others on here have noticed movement, whether as with Saffy who even showed on you tube, I think, how she could manipulate her abdominally mounted generator.

It seems we have a few of us around here with things that move and go bump in the night, and I hope for you, the solutino is quick in coming.
