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

Size: 3 Pack

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.

Buy it. Spend the $$$

Size: 3 Pack, Size: 3 Pack

Glad I spent the extra money and got the rollers with the ball bearings. The 3 pack came in handy. Very good quality. If you are doing more than 1 area, you will need these.
