As I lived in the DR for many many years, I know for sure most of the Cuban cigars are fake there, unless you paid 1500 pesos each. As most Americans hardly have smoked real Cubans they won't notice.
Better buy a good Dominican like Arturo Fuente than a fake Cuban.
I smoke one or two a day and buy them at www.cigarsofhabanos.com , cheap and reliable. I am pretty sure that if you ask them they will take of the brand.
