First of all- put original Kouros out of your mind when you consider this one. Other than name and perhaps some philosophical design similarity, Body Kouros bears no resemblance to Kouros whatsoever.
That being said, it is a fine fragrance. If I were 30 or under, it would be my main dating/going out frag. Not as commonly worn as Le Male and A*Men. It's sweet, but does a great job of staying just on the safe side of "too" sweet. Nicely designed scent.
I don't know if it's a "safe" blind buy, but that may be your only choice. No retailers in US seem to carry it. Sampling will be difficult.
It's probably a bit too young of a scent for me to wear much, but I like it a lot.
