Empty Promises

The tea my wife, 2 friends and I a total of 4 weeks, taken regularly. We made sure that we do not eat more than before. We were able to assess whether the tea has an effect. Unfortunately, we all had to find that we have not taken off with the tea. The promises, particularly in television advertising, which by a weight loss of up to 12kg in a month is mentioned, we can not understand, unfortunately. In our experience, there are only empty promises. The high price of the tea is absolutely no justification for us and we will therefore never buy it again.
