Bro,
I do not own a bottle of Aventus so i cannot compare it side by side, however ive tried Aventus from stores.
From memory, CDNI smells almost exactly like Aventus. I get the same smokey scent as i got from Aventus, but less pungent.
It projects a good amount and lasts long on my skin. It is a very strong fragrance and people will notice you.
Ive worn it outdoors on a super hot sunny Malaysia day, and it smells great. ( Just adjust your spray depending on the occasion and temperature )
To me, its very versatile and can be worn all day all occasion ( maybe not sports )
Also to note,
I do not like Aventus when i tested them in stores, ive tried couple of times, different days and i remember all i get is heavy smoke.
However,
I do like CDNI, it gives the same scent but is less smokey and less harsh than Aventus.
And the price Rm 120+- for a 100ml, go for it.

Thanks bro for your info. Planning to buy it!
