The Vibrating Peanut Ball Roller works well in relieving tight muscles. Typically, that would be the neck, shoulders, back and calves for me. I usually roll on it laying down but some spots such as the neck and shoulders, I can roll while sitting in my office chair.

At first it was painful. I used it on my lower back while on my stomach. But the relief afterwards is worth it.

This is exactly what I was looking for to put under my shoulder blades, mid-back and buttocks to relieve muscle tightness. I just lay on it, and roll it wherever I need it and just hold and it works great!

Great massage tool to use for knotted areas. It helps especially with my back and calves since it becomes tight. Also its easy to clean and keep near me so I can use it anytime.

I really like this small peanut massager, as it really is the perfect size for my neck, upper back and bottoms of my feet. Very firm, but I find I can tolerate rolling up onto it on my upper back. Helpful with pain too!

I bought this ball roller after hearing about it from one of the trainers at a local gym. I have an issue between my shoulder blades that's been painful and my husband has a problem with his knee. I thought I'd give it a try. It's very helpful! It's easy to use by yourself and the pain and stiffness in my shoulder blades are gone! My husband was shocked and pleased at how quickly it helped his knee. We're very pleased!!
