I used this to apply several different types of concealer to my under eye area with positive results each time. I was able to blend smoothly and precisely despite my misgivings about the larger size. The bristles are soft and glide over my skin nicely. Estee Lauder brushes tend to be of nice quality, and this is my pick for a concealer brush.
Pros: Soft Bristles, Smooth Application, Easy to Blend
Cons: The larger size will take a few days to get used to.
