This was a Christmas gift from my husband, and the only heat was found in the middle and lower back. I expected heat around the shoulders, and there was none! The massage feature was not desirable. It was loud and can barely feel it. And there are two massage balls that are pinpointed on each shoulder blade, so it was kind of uncomfortable laying on the wrap. I returned it and would not recommend this product at all.
Bottom Line: No, I would not recommend this to a friend
