A little rough...
This product is exactly as pictured. It comes with both an inside plug and a car adapter so you can use it at home or on the road. It gives off heat when it is on, but it doesn't give off very much so you can't really feel it when you're wearing clothing. The massage balls inside rotate clockwise and counterclockwise and they are very strong--sometimes too strong to the point where it's too rough and it hurts. I use it for my back, shoulders, and neck so this is just my experience in these areas.
