I love this machine. I suffer from migraines and this truly helps. Most of them are tension migraines. I put the attachment on and it just eases them right on out. The even give you a heads up which head is best for which areas. You don't need to do it very long however the longer you have it on the speed increases with it. Works wonders on the mid to lower back with the ball the neck has like a fork which really gets the muscle that runs next to the spine. I even like how it comes with a really nice case to store it all in. This is a great product specially for its price.
