I went ahead and punched this roller due to a special when I purchased a 36sq ft Roadkill Bulk Pack. I could have done the job without a roller, BUT, It would not have gone as easy or as successfully! Based on other reviews the first thing I did was tighten the end nut of the roller with a socket. The net is a nylon locking nut. I had no problems with it loosening. This product can and will bend if you apply a lot of pressure, to me this was a non issue. I think if you are just going to do a few vehicles than you can't beat the value of this roller. If I was a professional installer I might would want something more. I do feel like I was able to more successfully apply the sound deadener with the roller. I was able to roll out air bubbles and achieve good solid adhesion. So far I have only used it on my four doors. I do recommend some sort of roller for installing sound deadening.
