There are of course higher quality brushes out there for long-standing professional artists, but for someone like me who dabbles in art now and again, this set is more than adequate. What interested me in this set in particular was the variety of brush shapes - not just the sizes. The angled brushes in particular have a calligraphy quality that allows for both precise and less refined strokes without having to change brush.
My wife has also been using brushes from this set, touching up bits of paintwork around the house, which again the various shapes are helping keep neat and under control.
