Can't say it's completely useless. You will eat less and shape when you put it on, but it will be useless when you take it off. As before, ordinary body-shaping underwear can also achieve this effect. There is no need to buy Mei Ting's underwear, which is so expensive, and once you buy it, there will be many sales calls, many of which are deceptive. This is a personal experience ... I will never be fooled by them again.
