The Jeanie Rub Massager is a commercial quality massage tool that surpasses any muscle massager found in a retail store. I purchased one when I worked in a chiropractor's office 35 years ago and the cover just came apart so it wasn't useable. This is my second Jeanie Rub and I and my family members will get a lot of use out of it for the next ?? number of years. It's invaluable for chronic back and neck muscle tightness. I highly recommend it.
