I just received samples of both from Luckyscent a few days ago and was totally unimpressed with both. Molecules 1 I couldn't smell anything ... and I mean ANYTHING. Extremely weak for whatever it's supposed to be. Escentric 1 was a little better but still very faint smelling to my nose ... and absolutely gone in less than half an hour.
Definitely a "sample before buying" line ... but WAY overpriced for what they are, IMHO.
