i had a foundation brush when i use to wear foundation.. used it for awhile but then started to notice streaks and didn't clean it that often. now if i put on foundation i just use my fingers. i feel that it is faster, easier, and goes on way better. just wash your hands right before you are planning on doing it. i think it really depends on what you are use to and like. i made a thread about using fingers for foundation and everyone said that there was n/p using it as long as your hands are clean. and surprisingly many of us use our hands instead of a brush!
