Adopting the global patented "dynamic micro-electronic slimming technology", you don't need exercise or change your diet. This technology can make your local muscles contract spontaneously when you use it, completely simulating daily exercise, and use it for 30 minutes every day, which is equivalent to completing 200 sit-ups or 30 minutes of running. If you continue to use it, you will get the same effect as exercise to lose weight, which is more effective and healthier than medicine to lose weight, and will not rebound.
