I bought it for my wife thinking it'd smell great on her, knowing that I could occasionally wear it too. There was something about it that entranced me. She doesn't like it much (strangely enough she says it's too masculine!) even though I think it smells great on her. So yes I've worn it a few times. Haven't had any positive or negative comments. I think it's perfectly unisex. Haute concentree so yes the longevity is good.
Of the Lutens, I would only wear this and Chergui.
