This product is AWESOME!! to be sure. The 3 sizes you will come to appreciate, as I did. They have some 'heft' to them, and the ribbed rollers are far superior to the flat rollers. I just finished installing sound/thermal mats 'under' the rear speaker shelf of my '71 spiffy GTO. Tomorrow, I expect to do under the rear seat, and I am sure happy that I have three different size quality rollers. Buy these, you can't go wrong.

High quality tools

These are real nice. Pretty heavy and work well. Not some light weight junk tool. I’d definitely recommend these for ….. well I was sound deadening my car, but yes these were worth the money and will last me years if I ever have to get another set.
