I got none of the musk out of Musc Ravageur. The bing cinnamon roll opening and then...zero. I think it's some sort of anosmia on my part to that scent. I don't doubt that many find it fantastic.
MKK, I wore a couple of times and it continued to provide a creamy musk, but lighter on me than on a friend of mine.
Kind of hard for me to pass judgement on MR since I literally couldn't smell it.
