This product does what it says on the label. I used it after first combing through my Wire Fox Terrier's coat. The comb had removed tons of hair but when this was used afterwards, there was still lots more hair it captured. The only issue I have with it is that the pins seem straight to me and not ones with rounded, ball-like tips. Because our dog's coat is so long, I doubt the pins reach his skin, but using it with short hairded dogs may have a different result and irritate the skin.
