This silky-soft, dense little foundation brush is amazing. Using it feels like being nuzzled by a kitten. To be honest, sometimes I just swirl this on my face because it feels nice. My skin is sensitive and I use Retin-A, so irritation and microexfoliation are problems for me with most brushes. The little flakes my old powder foundation brushes kicked up on my face were driving me crazy. I needed to find something softer than goat but at least a little bit stronger than squirrel. This brush is the answer. I've had zero issues with microexfoliation since switching. Coverage is good and it works well to build up sheer formulas. It buffs to a nice, natural finish, no worries about looking cakey or powdery. It washes well and doesn't fluff much at all when it dries. The FO brushes I have dry a LOT faster than squirrel. The brush head is pretty small, so application does take a little longer compared to an average-sized brush, but in exchange you get a lot of control. It fits well around the eyes and nose. For reference, the flat surface is the size of a MAC eyeshadow pan.
