I used this pink belt, too. I used it myself for a while, and my waist has shrunk. I hope I can help you by sharing it with you. There is a straw bag with adjustable temperature, and then there are many massages and air pressure. It's very comfortable to squeeze. Just use it for 30-40 minutes each time, and your stomach sweats a lot. I persisted for half a month, and the effect was good.
