From what I recall from the Memo Irish Leather, I feel like it didn't last very long, so keep in mind the OG only gets 4-6 hrs. I think I will let this one macerate for a few weeks before coming back to it [spray a few times and put away in a dark place], but this one is a powerhouse straight out of the bottle. Very green scent, just like the original. There's a slight deviation on the dry down, which would otherwise be described across the board as "linear" with no real morphing, but overall great dupe.
