I have a "horrible" back….been on disability for years….I have had 2 failed major back surgeries…with rods etc…I bought this a few months ago and I love it! I think my favorite way to use it, is to put it on my couch or bed and lay flat on it! Between the massaging and the heat….it gives me some relief….even more that my strong pain meds give me! I might just buy another one….just to have as a spare for sometime down the road, if this one ever gives out. I don’t want to be with out one…ever! ..More
