While it looks the part, it sure doesn't act it!. All it does is smudge the chalk around the board, without "pulling" any of it off the board. My daughter uses a microfibre cloth for her chalk board now. While it doesn't look the part, it does remove all the chalk! The chalk eraser isn't a complete loss, as we've discovered it works better as a white board eraser. Still not great, but atleast it works on the white board unlike the chalk board.
