Friend put on a single spray of this cologne and I'm still getting compliments 2 days later

So I was in school with my friend and he put on a zara cologne called FASHIONABLY LONDON ELIXIR, but he put only one spray on me. Behind where I was sitting, there were a few girls about 3-4 feet proximity from us and they were sniffing their friend thinking it was them who smelled nice until they realized it was me and I got a compliment. Later on, at night so about 4-5 hours later, I still had the smell of the cologne on my shirt and met with different friends who still did smell it on me and really liked it. Now since this shirt had the cologne smell and since it wasn't dirty I had it hung on my door. Come 2 days later, I had a few guests come over and they entered my room asking what the nice smell was and at first I was confused, so I asked one of the guests who were my age so it wouldn't be awkward saying could it be the smell on the shirt and after they smelled it they said yes it's the same smell that was in the room. After all this I'm really thinking of getting this cologne as my next one, anyone else have any experiences with this cologne or like this with another cologne?
