I started on it on Wednesday this week, after seeing a link on facebook. Have only ordered a month to start, as it says you should know by then if it'll work for you.
I like the fact that it's all natural, and also that they have their own website so are more likely to be legit.
Will let you know how I go....only downside was waiting nearly 3 weeks for it to get from the UK to OZ, so if it does work will have to keep well on top of the ordering.
