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.

A Must Have For Sound Deadening Materials
Size: 3 Pack
I applied Silex sound deadening material to the rear interior of a Ford Maverick truck cab. Lots of narrow areas, and lots of curved surfaces. This set was a must to properly apply the mats to the metal surface. There were places that I had to push down with my fingers due to obstacles like seat belt mounts, but I could tell that I was not getting the same results as I was with the crimped rollers.

Would recommend
Size: 10 sqft
I used this sound deadening material in my car during an audio and interior upgrade, and the difference was noticeable immediately. Road noise, vibrations, and rattling were reduced a lot, especially on the doors and floor panels. The car feels much quieter and more solid while driving now.
The material was easy to cut and apply, and the adhesive stuck very well without peeling up. It has a quality feel to it and conforms nicely around curves and tight areas. I also noticed my speakers sound cleaner and have better bass response after installing it.
For the price, this sound deadening material is a great value and definitely worth it if you want a quieter ride and better overall sound quality in your vehicle.

Worth it!
Size: 50 sqft
I was worried it wouldn't work as well since it's 50 mil and I thought I got the wrong thing. Nope! Works great. Did all four doors on my 93 civic and I have enough for the floor I think. Solid price. Noise reduced by about 5 decibels hive difference. Very sticky and easy to apply I'm so happy I was able to cover most all of my car. If I need more, definitely buying this since I got so much extra and I thought I would.
PS: that five decibel thing is only with the four doors. My firewall is next and then my floor, but it's such a huge difference
