10 Pcs Car Sound Deadening Self Adhesive Mat, Auto Butyl Heat Insulation & Sound Dampening Pads, Audio Noise Insulation and Dampening Mats for Car Hood Ceiling Door, 9.76x7

Poor quality, not effective!

Easy to use, they seem to reduce the noise.

Works as should but not as good as the more expensive ones

Poor. No better than a mouse mat. No weight to them so completely useless. Avoid.

The 10 Pcs Car Sound Deadening Mats are a solid choice if you’re tired of your car sounding like a tin can full of marbles every time you hit 60 mph. The butyl base is much better than the cheap bitumen alternatives because it won’t melt into a sticky, stinking mess when the sun actually decides to shine. These pads are surprisingly easy to peel and stick, and once they’re rolled onto the metal, they do a brilliant job of killing those annoying vibrations and road hum. The 10-piece pack gives you enough coverage to tackle the "trouble spots" like door panels or the boot floor, turning that hollow "clang" into a reassuringly expensive "thud." It also acts as a decent thermal barrier, helping your air con or heater work a little less hard.
