When he's not beating up prostitutes, the ShamWow guy, Vince Shlomi, 44, has a day job of promoting ShamWow products. These towels supposedly have the amazing ability to soak up vast amounts of liquids of all types. The only problem is that CONSUMER REPORTS tested these $20 set of cleaner uppers and found that cheap sponges work a little better.
In a product test conducted by CONSUMER REPORTS, the ShamWow products will soak up milk equal to 12 times the weight of the claimed "supertowels". However, other liquids top out at 10 times the weight of the towel. Cheap sponges did a little better than this according to CONSUMER REPORTS. That's not a high recommendation for a much higher priced product.
However, ShamWows are more towel-like unlike sponges. So in that regard they may have other uses. So it's really up to the consumer whether a $20 ShamWow set is really better than some cheap sponges.
