I've only briefly sampled. My impression of it is:
- it is quite a bit different than the Concentre
- it is inordinately short lived
I seem to remember you like a lot of colognes which are generally pretty fleeting scents. You might really like it.
I don't think it is so similar to the Concentre that you are "buying the same scent." Let's see what others think.
If it's a decent price, it is one of the most highly regarded scents. I sought it out for a time and opted out due to the reports of no legs from so many noses I trust.
