Emmmmm ... Let me tell you this, many friends around me said it was useful, and there were advertisements on the travel channel. I bought a course of treatment with a grain of salt under the recommendation of customer service, saying that it was 30 days to lose weight and 30 days to consolidate, that is, 60 days, one paste a day. What about the price (598)? Not expensive, medium. Then I have used 40 stickers now. On May 4th, it was 130 when pregnant, and 1 15.7 kg after giving birth. Now I have used 40 stickers, and I have 109.3. It's useful to say it's useful, but it's useless to say it's useless, because anyway, I think I spent 600 yuan and lost five or six pounds. It doesn't matter. I didn't have much hope at first anyway. Parents who want to buy it should consider it first.
