I was at a concert last night and the man in front of me was wearing it. It brought me back a few years, as I hadn't smelled it in a while and was surprised that someone was wearing it. I can't say I hate it...but I can't say I like it either. But it certainly is distinctive. Then again, something about it is all wrong. It's like the pine tree air freshner of men's colognes. Whatever you do, don't unwrap it all at once, or you won't be able to drive your car without rolling down the window. Know what I mean?
Amazing sillage and longevity might be attributes some are looking for and get in it in Joop!. Others don't, so they will rule it out and choose... Aqua Di Gio, for example.
In my case, I am among the first ones; however, I am a sillage-conscious user living in a place were dousing oneself in fragrance is criticized but tolerated. Thus, whenever I use it, I go easy on the trigger. BTW, I also like it because I find it more complex than the average present day fragrances.
I'm one of the haters. I tried to like it: I really did... I bought it once and gave it away. Some time later I bought it again and tried to get myself used to it and then it got stolen from my work desk. I shed no tears. The sillage and longevity are the reasons for its popularity IMO.
