Haven't smelled SMW but I have Rasasi Al Wisam Day which is a twist of SMW. They're both worth having IMO.
Opulentia put me off when I first sprayed it and smelled it close but the magic happens in the air. I'd suggest not smelling it up close which can give you a slight detergent vibe but in the air it smells absolutely fresh, vibrant cooling soothing feel. I love this stuff.
Hoping maceration will only make it better. Packaging is okay. Bottle is very good. I was getting whiffs of this stuff on clothing after 8 hours.
Awesome one day delivery from Perfume Online. Upon first spray, this instantly reminded me of Blue de Chanel. About 15 minutes later the magic began to happen. I seriously felt as I was out in nature backpacking in the beautiful mountains. Every wiff I would get made me feel so good. I just love this stuff. I haven't yet tested it's longevity, but if it only gives me about 4-5 hours, I'll be happy because it's so worth the time that it lasts. Again, beautiful stuff!
