Query: strips the undercoat

The product info seems to dance around this a bit. This tool removes the undercoat. The undercoat keeps your pet toasty when it gets chilly. I don't mind the idea of removing undercoat hair that has already come loose but this thing strips it all out. I bought one, tried it briefly, then tossed it. I have a coworker who told me they got rid of theirs after his wife absentmindedly combed their cat while on the phone. The result was a kitty w/ a bald spot.
