I used a few of the brushes yesterday and today. They are interesting, especially the blush brush because it's more of a flat shape, not rounded like the duo-fiber brushes that we may be used to, so you sweep the powder on, like a face broom and as a result you get a heavier concentration of color because you're using more of the black hairs.
I haven't used the powder brush yet, but I just visually compared it to the MAC 187 and the 187 is just denser with more white fibers, which one of the reasons it's good for liquid products, because it is actually firm and dense. The Enkore powder brush on the other hand is not sparse or anything, it's just not as full of white fibers, but the cool think about this brush is it's shape; the black bristles are shaped just like a normal powder brush (the MAC 150, but less dense than that) and then there are the white fibers, so apply powder differently because it is white fibers are tapered and in the same way that the black fibers are as opposed to the 187 where all of the white fibers are the same length, meet at the same point, and have the same shape. The 187 is basically flat topped, whereas this is not. I would use the Enkore brush for my MSFN or a finishing powder, but I don't/wouldn't ever use my 187 for finishing powder.
And my favorite of the bunch is the Pointed Blender Brush. It's great for blending the small area of the crease or laying down a very concentrated color. I want multiples of this brush and I can't wait to try the other crease brush that'll be released later this month.
