I did get a sniff of this the other day. I agree with you, the top notes were excellent. Oddly, after about a minute or so, it seemed to go a little peculiar - it's possible that I don't go for the middle notes.
BUT... this also was on a card; I had tried so many things that day that every body part was used, so to speak. So it's not necessarily valid, because I didn't actually wear it.
I haven't had any luck with recent Kenneth Cole frags, but this one might be different. Let's see what others say.
