Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!

so uncomfortable
Size: 9, Color: Champagne
These shoes are cute but UNCOMFORTABLE. The toe thong makes them impossible to wear. I wore them for 5 minutes just trying them on and my feet hurt as I’m writing this. Couldn’t recommend less. Plus, the holes that the strap fits through aren’t lined up properly and are difficult to poke through. Felt like I got the made in china version.
