I have tested Lui, Patchouli, Vetiver, Mazzolari (Signature) and Alessandro and they have all EdP-like longevity. Patchouli and Lui last about 12 hours on me while the others last about 7-9 hours. All of them are quiet strong and have good sillage. Vetiver is a very refined and elegant floral take on vetiver, Alessandro a nice but slighty feminine heliotrope frag. Both are more subtle than the heavyweights Patchouli and Lui. As I said a couple of times before: the whole line is excellent and deserves more attention.
