I've not had personal experience with them, but I looked into their scents in my early "exploration" stage. As I understand, they have rights to the names and either have original formulas, or attempt to recreate the scent. I hear that it could be hit or miss as far as "sameness" is concerned, but the fragrances appear to be quality ones, rather than cheap knock offs.
I think I first heard of them via Now Smell This (not sure). I was not pining for any of the discontinued scents so I stopped my research there. As I recall, they have reasonably priced minis.
I hope somebody else chimes in!
