Toyota Camry

Review
I feel that doing some sound-proofing mats to at least be considerate and not be so noisy, since I refuse to turn down my music. Loud music had always been the habit since young. After much thought, I went forth to get some sound-proofing mats. The StandartPlast Alum had done a great job so far of sound proofing my car. I am satisfied with how it had improve music quality inside my car, plus reducing noise from outside the car.

What I like
Not too expensive, helped attain better music quality.

What I do not like
There's nothing much that I didn’t really like, except for the slightly unsightly mats on the interior of my car
