At risk of repeating what I have said in my other reviews of Real Techniques brushes, they are very soft, very affordable, and attractive to me because they are synthetic and cruelty free. I have had this set for a long, long time, and some of the brushes I use quite often. Here are my thoughts on the individual brushes in the set:
-Contour Brush: I do like this for cream contour because it allows me to be precise but also to blend out harsh lines. I've also used it for setting the under eye with powder, which it is great for given the slightly tapered, oblong shape. It is nice for highlighting as well, though I do have to be careful to not go overboard. 4.5/5
-Pointed Foundation Brush: I find this one way too small for a full-face foundation brush, but the pointed shape is nice for getting into small areas around the nose and the corners of the eye and such. I prefer a damp beauty sponge to apply my foundation, so I rarely use this one. 3.5/5
-Detailer Brush: This one is great for applying concealer before buffing it out since it is small and slightly pointed at the end. I also sometimes use to to clean up the outer edges of my eyes after applying shadow using concealer, and in a pinch I have used it to set my eyeliner or apply shadow under the lower lashes. Because of the shape and size, it ends up being very versatile. 4/5
-Buffing Brush: This is my favorite brush from the kit, and I use it very often. It works really well for foundation application or for buffing out concealer after it has been dotted on to spots. It is soft to the touch and somewhat dense, though not too dense as to make application streaky. I have washed it dozens of times and it still holds its shape very well. 5/5
-the case: cool concept, not so useable for me personally.
Even with the minor fail that is the foundation brush, this set is a steal at $12.
