Hello, Sorry to hear this. This is not an electric shock. The 4-pole head is a radio frequency head,If the energy is turned up very high and it is suddenly placed on the skin, it will feel like a touch of pain because it generates focused heat. To operate the RF head, you can first adjust the energy by 1-2 levels, then apply the product, touch the skin and move it slowly. If you open it up all at once and put it on your body, few people can bear it. 

Hello, The 80k fat-blasting head will gradually feel warm as the frequency increases, but it won't be particularly hot. As long as you feel the frequency sound, it's normal, so don't worry.
