Review on 🚘 Noico 80 mil Car Sound Deadening Mat: Premium Butyl Automotive Sound Deadener for Audio Noise Insulation and Dampening - 36 sqft (3.4 sqm) by Tanner Miller

Very very good product. Bought 3 boxes (36 square feet each) to rebuild my 2013 Toyota Avalon. I only used 2. My father (an ex auto mechanic) and I installed it on all floors and in the trunk. It took about 7-8 hours from start to finish. We didn't put it in the doors or the roof. Using the decibel app on my phone, I recorded the following decibels before installing it. Idle - 31dB, 35mph - 52dB, 70mph - 72dB. After installation my idle numbers are 31dB, 35mph - 35dB, 70mph 53-58dB (depending on road conditions). I also have to change the tires, after that everything should be even better. Note that the material may have razor-sharp edges after cutting; So wear work gloves.
