If your shoulders and back are hurting and you are in need of a message but do not want to pay the expensive prices by going to get one, then this massager by ShoulderFlex is for you. I bought this because I was sick of paying for massages all of the time and was constantly hurting in my shoulder areas. This is actually the best messager that I have ever owned, it works great and does a great job of providing you with the relief that you need in the areas that you want. This is very easy to use and it is small so you could actually use it on a lot of areas of your body. I like that it has different settings on it so you can control how fast it goes so you can have a nice slow roll on your shoulders or you can make it go a lot faster if you prefer it that way. This provides you with instant relief at night after a hard day of work and it literally makes all of my stress melt away so that I can feel better and be able to spend more time with my family.
