Let's get one thing cleared up here... This isn't a masterpiece. This is a clone, and a clone can't be a masterpiece. That's like saying that taking a picture of the Mona Lisa and printing it off on your laserjet is like seeing it at the Louvre. That's just not the case.
Evaluating the fragrance on it's merits, I'd say this does a very good job of copying Aventus but it's definitely not as good, especially at the start. It smells harsh and offensive in the opening, where Aventus doesn't. After around 30 minutes, it really settles down nicely. Masterpiece... hell to the no, but like I said, it does do a great job cloning a masterpiece.
