From what I've read elsewhere this is an oriental fragrance with amber, vanilla, woody notes, fruity notes and floral notes. I got the roller ball as I love orientals.. well most.
Bakhour started very strong, room filling even. I have acidic skin so that may affect how it smells on me, but smelling from the bottle itself it's still the same.. I get a sharp sour smell like moldy roses and sour lemons, a touch of greenness and I can tell there is sandalwood hiding in there also, but I dont detect any vanilla or any sweetness. It's a very heavy scent.
I've been wearing it for about an hour and the sillage is still about a foot away from me and the scent itself hasnt changed. I will be washing it off soon so cannot tell how long it would last.
I'm sure there are others who would love this but it is not for me.
