Query: Very disappointed.

We got the MediRub Foot Massager to counteract the effects of neuropathy primarily in my wife's feet as the result of chemotherapy. Although the machine seems very well constructed, all it does is vibrate. There is no "massage" to the action at all. The bumpy surface may keep your feet from slipping off, but it has no independent effect on the feet at all. Unfortunately, I threw the box away after we opened it or I would have sent the item back for a refund. It is a pretty expensive apparatus.Bottom line: if you want some kind of "massage" action, do NOT get the MediRub Foot Massager
