I have compared this side by side (real time) with Layton and I can’t smell any difference at all!
This was a blind buy for me based on all the positive reviews I have read about Layton. The notes looked good, and very important to me, they didn’t include amber. (It seems like today amber doesn’t mean labdanum, benzoin and vanilla, instead, it means amberwood which I really don’t like.) I was disappointed a bit when I got it, because I could smell what I think is amberwood. It is toned down to a level that I can wear without the need to wash it off. Then I ordered a 10ml decant of Layton for comparison. Side by side they were indistinguishable to me. If you like Layton, you will be very satisfied with this.
Every thing I have purchased from Zoha has been very good quality and extremely close to the original!
