I don't doubt it. And I have indicated it is sometimes called for. Everyone needs to do what they think is right as far as spanking are concerned. Also, Spanking and beating are two different things.
So, did you look at the photo and the ad for "The Rod?" It's a whip...nothing more and nothing less. Are you OK with using a whip on a child? I'm sure not, and I'm in favor of spanking, when necessary.
This thing will land its user in jail if they get caught. I guarantee it.
