Interesting your reaction to it.
I must admit to being puzzled with it the first times I tried it. Firstly, the bottle is very hard to tell apart from the female version (which has a slightly darker coloured bottle, and an F on the cap instead of an M - which isn't of much use if you buy the tester without the cap).
The men's one starts out a tad feminine and then transmutes to something more masculine. The women's one does the opposite. I initially thought my ladyfriend and I had mixed up our bottles!
However, when I finally gave it a full testing out one day in the office, I was very impressed with it - this chypre put a certain zing into my day.
