Bests & Worsts Reviews from Amazon

Very very good product. Bought 3 boxes (36 sq. ft. each) to do my 2013 Toyota Avalon. I only used 2. My dad (former auto body guy) and I installed it on all the flooring and in the trunk. It took about 7-8 hours beginning to end. We did not put it in the doors or roof. Using a decibel meter app on my phone I had recorded the following decibels prior to installation. Idle- 31 db, 35 mph - 52 db, 70 mph- 72 db. After installation my numbers are Idle- 31 db, 35 mph - 35 db, 70 mph 53-58 db (depending on road conditions). I also need to replace my tires, so it should get even better after that. Be aware that the material can have razor sharp edges once trimmed; so wear work gloves.
