For lazy (like me) just right, I am very satisfied and have already recommended it! Just do not overdo it and choose a lighter level (otherwise there may be a small pain) it with the use (steps). The advantage is that is not only punished but also the abdominal wall tissue (skin). With regular use you quickly lose a few cm. One can belt with the housework or even (now in winter) wearing super when going for a walk under the thick jacket. The only downside I had found is (unfortunately that is not in the description) that it stimulates the activity of the intestine ..... Nagut are indeed worse. A few more advantages: no extra gel, water ran onto the skin belt and you're exercising at;) My belt was after few months his ministry not do .... Have the company written and get a new one. That's what I call customer service !!! Best part! We recommend!
