Awesome for the middle of your back but doesn't reach the very lower back or top of the shoulders or neck. Don't over use at first or your body will be too sore.

I bought this massager for my husband and i have used it a couple of times too, although i did try at the shop but at home u cant pleace on a sofa or a seat with slightly tilted back bcoz the massaging gets a bit too hard it starts hurting the back intead of comforting. We now place a towel on the cover which reduces the strength of the massaging action. As for the nack massager its the same cant tilt back ur head or it gets hurting ur neck. Not too happy with my purchase overall.
