I had it, but swapped it away. I kind of regret it though, I kind of miss it, but I didn't wear it enough. To my recollection, it was very much along the lines of Gucci Envy, with a strong tea note, and a different type of incense. I'd say Envy is more suitable for cooler weather though, while Aura is more seasonal. There's definitley a heavy dose of ginger in Aura too. It's got a little of this and a little of that, but overall, well balanced. Reminds me of a better version of Samba Heat, if you've ever tried this.. I believe it won some sort of FiFi award some years back.
Also, big points for the bottle. That alone was almost worth the 15 bucks I paid. A real statement of a bottle!
