I collect real ouds and have some perfumes with so called oud in it. I think duro has more of an oud smell then any other perfume. More then m7 more then any montale or le labo. Duro has a strong Hindi oud note in it. I actually have a Hindi oud called Indian spice and they compliment each other when worn together.
I don't know why people think the medicine note in montales is an oud note. Oud smells like a very complex wood note that sparkles. Duros strong wood note is the oud note! Duro is all wood spice and leather.
I think amouage epic man smells like a more complex duro light.....but that's even more expensive.
You can get duro for 100 and a little cheaper on eBay sometimes.
I am on my same bottle for the last years....and still have more them half left! That's my one cologne you only news a half a squirt and it stays on your skin for days!
