It is good and works well. But it's not designed just for weight loss. So be careful if that is your ultimate goal. You will lose weight but it's suppose to be for just cleansing the body and losing weight is a bonus to that. I did it for 7 days not 10 like some people.
My wife and I are doing the flat belly diet and it has a cleansing water that isnt half bad. Its lemon, cucumber, ginger and mint leaves. We drink 2 liters everyday with a light diet. The only draw back is that it makes you gassy.
