It has some similarities and some differences, but overall, for the low price of this dupe, I opine it's not worth getting the original given the short-lived performance of its current batches.
The ingredients of Infini Elixir do not smell of low quality, so it's not like the original smells pricier to my nose like what happens when comparing originals besides their dupes.
Lattafa's Infini Elixir is a really nice dupe that I enjoy more than the Fragrance World versions, which are also great for the price but much heavier on the sandalwood and saffron; too cloying for my taste.
