It's ok. The item rolls along your back or wherever you use it relatively well. I don't know if somehow I'm just not positioning right or what, but it just isn't doing much at all for my back. I have the deep tissue one, which I heard should be the best, but it doesn't pop anything in my spine and doesn't really feel much different than someone running their palm up and down your spine to me. I don't really feel it stretching my muscles - just kinda flattens them while it rolls. I am for, and I watched the videos on how to use it, so no weird circumstances either. I guess I just don't get the difference it's supposed to be making.
