I have had my finishing mist for a looooong time. I use it quite frequently, so it lasts well. I normally just mist my face after applying makeup, to help give my skin a slightly dewy finish and to "merge" all the elements of my makeup. Although I absolutely love the formula, I don't particularly love the pump - it delivers more of a spray, rather than a mist. I wish the "mist" could just be finer.
Overall, I would definitely recommend this product, as the pump issue is an easy one to work around, and the formula itself is great!
