I loved everything about this product. I don't have 1 negative thing to say about it. Honestly I really tried to think of 1 thing that I didn't like and I couldn't find one. The package is great the materials that are being used for this product are amazing and lastly is, it just works so well. Super easy to cut and customize the shapes you need to lay down. Just take your time installing it and don't rush yourself. Make sure you have a ROLLER when doing this because it will make installing this much easier and quicker. I used it in my 2024 GMC SIERRA CREWCAB and it made the truck nice and sound. That tinny / rattle noise is gone. This was enough for me to do the back wall of the cab and the amp rack that went behind the rear seats, the doors and some spots just around the front dash area and a little bit on the floor but I didn't do anything on the roof. I wasn't trying to tare down the headliner yet, maybe later I will but again for 10 sheets of 18x32 this package was 💯🔥🫡🤝🤘🤙🤫
