Review (4/5): Works for  most brushes
This doesn't work as great as you may expect. If you have a brush with those little bulb like things on the end of the bristles, this doesn't get the hair out for those. It brings it to the top, but you still have to get it out by hand. For a different brush without those, it worked amazing! It is very sharp though so be careful...I stabbed myself. Overall, still better than what I was doing before (my hand)
