I only own M by Vasnier, forget what it is (I think series 3 no 6), a dirty-clean leather - ie it has both a lot of animalics and a clean laundry musk. Interesting but not the stuff of dreams - too much white musk - if it had been dirtier, it would have been very good. I also found Nicoll (or something like that), a bright fennel-veggie, and solar donkey (bright citrus) interesting. I think there's also an incense some people like (Ascent ?), but I thought it was like many others. The rest didn't really register much with me. Overall it seems it's just not worth the price. Cute packaging though.
I have not smelled yet series 4.
If I remember correctly, there were a couple of past threads about some of them.
