Have both, and the PM is certainly more subdued than its brethren (this is a good thing, imo), but longevity is still a solid 6-8 hours for me. Not the 9-12 hours I get with the original, but certainly well within acceptable range. Perhaps you're misconstruing its lack of projection for a lack of longevity. It quiets down a bit after the first hour or so, but is very noticeable for quite a while after that. I sprayed one solid spray on upper chest/lower neck the other day for work, and could still smell it under my collar just before going home for the day. For the record, this is with the new "limited edition" bottles. Did you ask anyone else if they could still detect it on you?
