A smell-a-like is a perfume that smells like a designer fragrance but with a different name and packaging, and at a cheaper price. A smell-a-like isn't an exact copy, but often smells very similar.
Mankind is the most identical to YSL L'homme in every way, however, it does not last long either. But, for the cheaper price it is more worth it.
Not bad but it doesn't have that brightness as the original one which in my opinion is the most inviting element of YSL L'Homme.
