I like Diptyque scents and am very familair with BlueMercury - Im a big customer. But Tam Dao didn't do anything for me, either. Matter of fact - Im practically anosmic to it. Perhaps if I really paid a lot of attention to it everytime I sniffed it, it might eventually open up to me and become something extraordinary. But you know what? I just dont have that kind of time. Too many other scents to try - not worth it to get hung up on one...
I love L'Ombre dans L'eau, however. An extraordinary green rose!
