No good. Real review.
At 1st thought it would be cool but it's just a mini electric shock. Also somebody else cannot use this on u, idk why not but it doesn't shock u if some1 else is holding it... also the handle may shock u while ur holding it. So u can even get a back massage with this bcuz u can't reach ur own back. And it's real light and feels very cheap and low quality the way it rattles and feels.  The other machine where u can charge it and it has the sticky electrodes that 1 works way better.
