I ordered one for my wife, it just arrived today. I agree with OG, the smell is definitely burnt hair; however, even though it does not smell "bad", I would be hard pressed to say it smells good. Ironically with the Arizona heat, as soon as we opened the box, we could smell it!
Overall, I think I am going to have a hard time to convince my wife to try it, so it's likely going to stay a collectible.
I never had to spray any either. I just opened the box to check it out rather quickly and my house still has a little burnt hair smell lingering around. It does have a fancy smell to it. I could see a grandma wearing it in some elegant atmosphere. I’ve seen online that people are saying it smells like a campfire. Some unboxing videos are pretty funny…
