I was actually surprised by how much I ended up liking this brush set. I had seen it, along with the rest of the Real Techniques brushes, in my local Ulta store and was unimpressed. I didn't feel the need to have it just judging from the way the brushes looked in the packaging. I finally bought it just out of the need of a good concealer brush, which I was hoping the deluxe crease brush would be. It turned out that I love both the deluxe crease brush and the base shadow brush. They're some of my favorite brushes to work with in my collection and just those two brushes basically justified getting the entire set, even though the other brushes were not so great:
Base shadow brush-This is basically the synthetic version of the Mac 217. It is flat but rounded to a point, like the 217 but its probably slightly less dense. This is fantastic for blending cream products like eyeshadow bases or cream shadows. It would be good for concealer too if you want a light coverage. I don't like to use this as a blending brush for powder because the Mac 217 is much better for that since it's made out of natural bristles. But I love it for blending cream products, it does a fantastic job!
Deluxe crease brush-This is an unusual brush to find but it is basically a stubby but rounded brush that domes to a point. It's on the dense side and closes in shape and material to Sigma' Precision Round (P82) brush. I cannot tell you how wonderful this is for concealers. I've used this with both cream and liquid/highlighting pen type concealers and it just blends so perfectly. The shape is perfect for getting into the inner under-eye area. The synthetic bristles blends my Mac Studio Fix concealer perfectly and builds the product on well.
Accent Brush-This is a tiny round flat brush that is pretty handy for doing any detail work. It would work for concealing small areas, going under the brow with concealer to sharpen the brow, cleaning up lip lines with concealer, putting highlight in the tear-duct area, etc.
Pixel-point eyeliner brush-This is basically a bigger script style eye-line brush. It's good for building a thick line quickly. It's also good for tiny spot concealing. I mostly use it for laying down gel liner thick and quick and then softening it with a smudge brush. It's actually one of my least favorites from the set that I can do without.
Brow brush-This is probably the worst brush in the set and one that I find completely useless for any application of make-up. There's basically no good way to use this brush for anything. It's a large and thick angled brush made with the same fine synthetic taklon as the rest. It does brows quickly but with no sort of precision. If I was going for a natural fast brow, even the Mac 239 is better. It's way too thick for use as an eyeliner brush. I really don't know what they were thinking with this one.
Even though only two brushes were standout must-haves for me, I feel that for the price and how good the two brushes were, that this set is worth it.
