It's a really nice oud and rose.
Coincidentally today I compared and constrasted it against Rosam by Histoires de Parfum.
The Kilian is a lush, decadent rose and oud. Perfection in the opulent league whereas Rosam is perfection in the minimalist guild for oud and rose.
And to answer your question. Yes the it does merit the steep price. The oud used is proper oud. The most proper I've smelled in a western perfume. But do smell Rosam before committing to anything.
Nice to see you postin here
