I love my E.L.F. Powder Brush. I've only used it for loose and pressed powders, and I've loved it. Many also use it for liquid foundations, but I haven't.. I've used it to apply my loose/pressed powders, blush and bronzer. If you are looking for a cheap, but great quality brush- this is for you. I would give this brush a 9 out 10.
I use it to apply bronzer to my face and this is my favourite face brush, the bristles are a bit longer than the studio powder brush and studio complexion brush. It is a bit more expensive than the studio brushes though.
