What every best has:
PopularMechanics.com puts Mighty Putty to the test by mimicking some of the claims made in the commercial. Most of their tests are successful, with the exception of sealing a leaky copper pipe and supporting a concrete block. A reporter at WBRE in Wilkes-Barre, Pa., has a completely different experience, however, with Mighty Putty failing nearly every test. Customer reviews on InfomercialRatings.com and Amazon.com are mixed, with some having great success with their Mighty Putty uses, and others claiming total failure.
