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.

Works great for sound deadening install!
Size: 3 Pack
I recently put Kilmat in my van I am converting. I thought I wouldn't need to get rollers to install the sound deadening mat in my van but I ordered these anyway. Why not, 3 rollers under $20.00 and I could return them if I didn't like them. Well I ordered this roller set. I was able to put the mat on and smooth it with my hands but these rollers really helped flatten out the sound mat to get better adhesion, especially where I overlapped the seems. The rollers were more necessary than I thought. They are very sturdy and work well. They do not feel cheap and I actually liked them quite a bit. The rollers have smooth function and leave little lines in the mat where I used them. This was very handy as it let me know where I had already used them. It was nice having 3 sizes. The big roller did not fit in some of the curved areas, so I used the smaller rollers. These will work well with sound mat that is thicker than the Kilmat as well. If you are installing sound deadening mat, you should purchase these. I saw other rollers that were more money and didn't have multiple sizes. This was a good purchase. I will try to add a picture to help with visualization purposes soon.
