I've only sampled Chene once, but I fell in love with it immediately. It has been on my "to buy" list for quite some time. Perhaps this fall, I will end up with a bottle of it in my collection!
I also own a bottle of Five O'Clock as well. I blind bought it on a whim, and I am glad I did. It's one of those that I thought I would like based on the notes, and I was right. I am slightly disappointed in its performance, but that's not a big deal for this type of fragrance.
