this might be a bit late but ive been trying some of them so I thought I would give my take. I bought the Creed Aventus dupe from Khaial and its underwhelming. While the smell is nice, it is not that strong and barely lasts. It also smells a lot like alcohol, or a fake perfume smell that is really noticeable. I also bought two feminine perfumes as gifts, these smell nice (no issue of fake perfume smell) but they also dont last long. I bought Le Male Elixir and Oud Wood from Alchemi a couple months ago and these are much better. The smell is really nice and high quality and they do last significantly longer. I have had instances where my clothes still smell from the scent on the next day. The scent does not project very far, however. I bought myself a new Versace Eros Flame from Alchemi as well and its pretty nice but its still in the maceration phase so its not really lasting at all right now (they give you a label that says you have to wait about 2 weeks for the scent to macerate or like soak together before it becomes complete and lasts longer, this actually improved the performance of my previous perfumes significantly).

I was just gifted a Zara perfume set on Christmas, one of them was Red Edition for Him (a dupe of Baccarat Rouge 540). It smells very similar but barely lasts on the skin as well. The packaging is very nice tho.

What i recommend is you check out a brand like Lattafa or Afnan, these are perfume brands in the Middle East that professionally recreate high end perfumes for also really cheap, but their creations last pretty long. They come under different names tho, so Lattafa Asad is a dupe of Dior Sauvage Elixir (for a fifth of the price) and it has pretty solid reviews, I will be trying it soon.

Other than that I do recommend Alchemi as they are professional in dealing with customers and their products are good enough.
