Okay, so I was skeptical AF when I ordered these sound deadening mats. Like, how much difference could some sticky foam sheets really make? But holy moly - my '04 Civic sounds like a luxury car now!

The install was stupid easy. Just wipe down the metal with alcohol (super important!), peel and stick. The included roller helps press everything down nicely. Did my doors first and immediately noticed less road noise and no more tinny door closing sounds.

Used about 20 sheets so far on floors, trunk and rear panels. Still have enough left for my roof. The adhesive holds strong even in Texas heat (unlike some other brands I've tried).

Pro tip: Don't waste time covering every inch - strategic placement on flat panels works just as well for killing vibrations. Saved me a ton of material!

Only complaint? Wish they included a few more sheets for big projects. But at this price, I'll definitely buy another pack to finish my build.

Final verdict: 9/10 - Crazy value for money if you want to upgrade your ride without breaking the bank!
