The ShamWow: does it come with more 'sham' or more 'wow'?

Consumers are fond of multipurpose products. But can you trust a product that makes too many promises?
  We're talking about you, ShamWow. Here we have a "super shammy" that can be used as a sponge on spills (it supposedly holds 20 times its weight), that you can wash your car with, or your dog, that you can use as a towel—after all, Olympic divers use it! You can even use it to seal leaks! (OK, they don't say that, but I'm sure it could work.)
  I thought the whole point of paper towels and sponges was convenience and the fact that they're disposable. But no, the inventors of the ShamWow think you'll buy it because it's machine washable, costs just $19.99 for four large and four mini ShamWows, and comes with a 10-year warranty.
  And if you're still not sold, watch ShamWow's low-budget infomercial (above) starring AdFreak fave Vince Offer, who gives the best sales pitch of all: "It's made in Germany; you know the Germans always make good stuff."
