I happen to like it, but don't like it enough to consider it bottle worthy.
It's primarily a fresh green scent, with some lemon and a fruitiness in the beginning. Just a little tart, and just a little sour. It doesn't get sweet or powdery, but dries down to a paler version of Cristalle. I wish it were more mossy in the dry down. Not a chypre by any stretch of imagination.
I haven't tried Bel Respiro.
