This EMS machine works very well. If you are looking for an abdominal muscle stimulator, then this will be your choice. It was scary at first because your brain told you no, because you knew you were about to get an electric shock. It is not that bad. I haven't reached level 5 yet because it was too intense. It has 20 levels. I will never live to be 20 years old. So if you think it might not work. I dare you to try level 20 and say with a straight face.
