Smelled recently again at the store in NYC. Absolutely wonderful, a deep, ancient smell, resinous, dry, rich. Despite the frankincense, it doesn't smell at all like the standard churchy incense.
I'll eventually buy it. The only little thing is that it costs a lot ($90 for 10ml oil), and unfortunately it comes in the hated roll-on, which is inexcusable for anything so expensive. (It also comes in alcohol format, which is cheaper, but it smells also lighter, less rich and deep, so I definitely prefer the oil).
