PEACE OF MIND FOR PARENTS
Relax: there's no need to buy a new car seat as your toddler gets bigger.

Effortlessly adjust the headrest and harness simultaneously, so you're always ready to get out and about - even if your darling's had another growth-spurt.

Best butyl out there.
Style: 30 sqft
If you want the money you're spending on equipment to pay off, you NEED to deaden sound! I've used every major brand and siless is my favorite to work with and the best value for your money, I'm not just adding weight, it's a thermal barrier and reduce outside noise.
I turned a 10 year old, base model civic into what feels like a top tier Lexus .
Does not offgas, no smell. Super easy to install.
Make sure you get a set of rollers! They're required to achieve the advantages of this stuff, it MUST be adhered well and you don't want to tear the interior out twice.

Worth every penny
Style: 6 sqft
Works great! I have a van and it took all the noise out of the rear doors. I am almost in shock at how quiet it is now.

Great for what it does but not a miracle
Style: 30 sqft
Sticks well. Definitely thicker and nicer than the Kilmat version. If I were buying again I would just buy more of this, the value is better even though you get less total coverage per pack.
Can be cut to size easily, we used a box cutter which got a little gummed but but not too bad. we were able to get it in and around everywhere we needed to put it and it held up well as we were mashing it into weird spots. It doesnt smell hardly at all while being applied and once its on there is no smell whatsoever The product is great for what it is. 4 stars only because I think it gets oversold for how much this alone can do. We did notice a slight reduction in noise but nowhere near the multiple decibels we see claimed everywhere. If your vehicle is mostly quiet but just has that little bit getting through this will probably do wonders, If you have a vehicle where there's significant engine noise in the cabin you'll need more than just this to bring that down.
