I didn't lose any weight while using Wulong Tea, but I had more energy, and a sense of well-being. I used the flavored loose tea (rasberry), and the taste was pleasant.
I think the tea is also filling, and something different to drink besides water. I don't have a tea kettle, so leaving out a pan of water on the stove and a strainer was a hassle.
Once I get a tea kettle, I will probably buy it again. The energy, from a safe and healthy source was worth the money.
