I own two Vie-Long horse hair brushes. One is a brown hair brush (12601) and the other is a white hair brush (13061b). Both are 21mm knots. I love these brushes.
I soak the brushes for maybe 60 seconds and only squeeze them at the base of the knot. I lightly swirl the tips while loading and do not apply pressure. I use paint strokes to build my lather and the feeling is sublime. I feel they perform on par with my badger and synthetic brushes. They just require a different technique.
I feel the need to add that I have coarse facial hair and my skin is not sensitive at all.
