Title: Not Worth The Free Shipping
Review: As everyone else found out, the metal parts bend as soon as I started using it. They also pull out of the wood handle very easily. The frustration of trying to install the dynamat with this...er...a...tool (roller would be an over-statement since the thing mostly rubbed the mat down) almost ruined the fun of getting the project finshed. I had to keep straightening out the metal pieces, assemble them with the wood roller, and jam the assembly back in the wood handle, over-and-over-and-over again. Really, just use your thumbs instead if this product. You'll have a better time of it.
