Even without a working link, I'm sure the product is either extremely dangerous, or doesn't do anything at all. You certainly don't want to be scooping earwax out of toddlers. A few years ago there was a wacky appliance on the market, it claimed to gently vacuum clean the ear canal right after bathing. It didn't do anything at all.
I'm sort of addicted to Q-Tips. Even though the experts say to never introduce an object into the ear canal, I do it with Q-Tips after showering. Doesn't seem to be an issue.
