I could attest myself of the longevity of the frag is different. Even using eau de parfum sometime my frag does not last long. Im wearing 212 right now and the smell is almost gone.

Sometime the perfume does not suit our body i guess. I like bvlgari perfume but i find that the smell wouldnt last long. 4-5 hours max and im using eau de parfum. If u wanna say its a triple A product, well i do buy my perfume at the department store so i doubt they selling the imitation ones lol.
On the other hand, perfume like dunhill desire blue for me last a tad longer even though its just eau de toilette.

Maybe its just me...
