Mostly I use the Buffing Brush - first for a fine layer Foundation, then for concealer under the eye (just the bristles squeeze a little, so you can work more focused and apply the paint more intense), then for powder and for facing of the contour and Blush. Truly an all-rounder!
The Contour Brush is just as great, so can be cheekbones, jawline, temples, forehead, nose, and eyes (again front squeezing) super contour. For Rouge I use this brush exactly.
The Pointed Foundation Brush I use mainly for highlighter under the eyebrows and on the cheekbones (the width is for super!), But sometimes also for concealer under the eye. I need him in the set does not necessarily mean good anyway, that he is.
And last but not least is the Detailer Brush super for all the little things that need to be done in the face so - small pimples cover, for example, but also a highlight in the inner corner of the eye can be super with it. As Lippenpinsel he is appropriately determined, only I do not use lipsticks and therefore do not need him for this purpose. You can follow the eyebrows with it, for it but there are better brushes.
All in all, there's a strong buy recommendation from me - I do not know what I should pull a star with this brush set. Clean it can also be very easily and quickly, and if you dry gently with a circular motion on a towel "rubbing", they are then only minimally wet and quickly ready for use again. Only necessarily lying down or leave (best) upside down to dry to prevent water coming in the stem, which could solve the glue.
