Pretty darn good. Reasonably priced
I received this brush very quickly, thanks Amazon. The brush goes through my thick somewhat frizzy hair very nicely.  The result of using this brush is, IMHO, soft,  silky hair. I didn't notice any stretching or pulling of my hair.  The nylon pins in with the boar bristles are a little scratchy but it doesn't bother me too much. My scalp feels "activated " after a good brushing of 50 or so strokes of the brush.
