I have been using this setting powder for years and I always have back-ups in my makeup drawer. The powder is finely milled and really makes a difference compared to the loose powders I used to use under my eyes. The only downside is the packaging: I have to leave the seal on to cover the holes because the fine powder is working hard to escape the container. I would suggest to only poke a couple of holes on the seal to save your product. Also, I find the brush to be quite useless and the bristles are too stiff for the job. I like to apply the powder with a really soft eyeshadow blending brush.
