Yes I own(ed) both Marbert Homme and Marbert Gentleman (versions as pic showed by Shamu1).
You can see both bottles upfront of my collection pics I posted some months ago in my profile as well on the powerhouse site.
I bought both during a trip with my gf to Koln last year September for 12 euros a piece, 100 ml.
In the meantime I already sold both for the same price as I didn't like them that much.
I bought Marbert Gentleman cause I have a mini bottle (see pic of my mini bottles) of that one which smells good but this new version is not a shadow of its former self. For me both are a herbal, spicy mess and one of them (Gentleman) now has a certain note I really don't like. Homme, (if I recall correctly as maybe I am mixing them up as I only sprayed them both twice and then already decided I had to get rid of them), smelled like a kind of very worse version of Chevignon Brand. Like a mutilated brother so to speak. Chevignon (Whiskey like bottle) is one of my fav, but Marbert Homme, is really bad.
Maybe those other versions smell different, at least the vintage Gentleman does.
And no, they both (newest versions) have nothing in common with Cool Water..............nothing!
