I have the sota mag pulser which I have found not so effective in the killing what ever it is that is I am fighting. It is not the same as a zapper. If you wash your face and put the butt paste creme on it before bed, get a good night's sleep, you would be amazed at how much better your face would be in the morning. This is no a cure, it is just one of the things that have helped clear my skin.
