Thanks for the tip. I can see how you'd see the similarity to Cuiron - I don't particularly like Cuiron and I sold my bottle ages ago but that was because a single note bothered me. I'm sensitive to some notes and that sometimes makes an otherwise fine scent unwearable - I have the same problem with L'Instant PH. I'm also a bit blind buyer - especially with cheap bottles like this.
I re-read your review and you compared it to Derby. I remember Derby being fairly overwhelming when I sampled it. Is Mr. Blass the same?
