There are two in my family, one is the belly buster, and the other has forgotten its name, so it can be used all over the body. I kept using it for 1 month, and it didn't work at all. Diet and exercise are still needed to lose weight. I used to be 150, but now I am 1 10. You'd better try to lose weight These things that rely on external forces are useless. Moreover, I saw that tvbi also broadcast a program to introduce these vibrators. Their principles are not feasible, and long-term use may be harmful to the health.
