I would pass on these
The plug part is too small so it makes a loose connection and come off the pad and then shock you. T hen you start to become a little afraid to use your unit because you think,  I am going to be able to sir perfectly still today so that I don't get shocked.  Also they are not as strong, maybe because the connection is so loose. If you are a gambler these are for you.
