Update: As excited as I was for this brush, within a few weeks I found the application to be patchy, streaky, and inconsistent. Funny enough, I purchased the #116 - I got a great one and am much happier. Perhaps this is better for contouring, than for blush.
I've tried the #116, which while I loved the shape and size, it was not soft enough, and with my sensitive skin, was making little marks on my face. Plus, with the pigment in most blushes these days, it created too much definition. I've also tried the stippling brushes, and to me, it was too much work to get enough product on my cheeks, as well as, I always had streaking. I've stayed away from this one, because I'm not a fan of an angled brush for blush, but the softness and size, was what I was looking for, so I broke down and bought it. I have to say, I am quite pleased with this brush for blush. The angle is a non-issue, I don't even pay attention to whether it's up. down, or sideways, but the softness and density for blush, is perfection. It's made putting on blush, so much easier and it looks great all the time, instead of every once in awhile. I see that some reviewers say it can get rough over time, but I've never had an issue with my brushes drying out or getting rougher. If you use cleaners that have alcohol or clarifying ingredients to clean your brushes, you might try a little conditioner or a little light oil every once in a while to moisturize them. Even if you think a brush is beyond hope, work some oil into it, let it sit for a bit (just like you would your hair) and then give it a light shampoo - you never know, it might bring it back to life.
