I love it! I prefer to use this instead of gel or creme liners. It really does last all day.
At first I was skeptical, this brush looked like it wasn't anything special but to my surprise after using it on customers I fell for it. It's my favorite foundation brush, it blends perfectly. I love the stiffness to it and how it's on the smaller side. I recommend this brush to everyone. Also you can't beat the LIFETIME warranty on the Studio Gear brushes.
