Hello: I have used it and it is very effective for my health. But it must be done according to the procedure. Stick to it for a long time. I have used it for several years. I'll do it if there's any trouble. Recently, a lump was found in the chest of the upper body. It's been done for three months, and now there's a small piece left, still making it! I replied that you didn't come to answer the questions and receive the prize, but I couldn't send this message without writing the prize? As for the use of time, it is not easy to use it when it is not used. That is an irresponsible attitude. Because your body needs healthy cells every day, your cells can't be well filled when you don't use them. No charging, no detoxification. It's normal to go back a long time. Want to buy, want to use, want to be healthy, and make up your mind to stick to it for a long time. The human body needs to eat, and cells need to be recharged. Today, a friend asked me about the function of the negative ion therapeutic instrument, so I came to check the information. I gave you an answer when I saw your news. When you do it, you should follow the prescribed time. What should the body pay attention to when it reacts? In a word. Be sure to follow the instructions.
