Anker USB C Hub (7-in-1) I now have several Anker Products in my home. These folks just know how to build products. Affordable and durable, stable and easy to use. This 7 in 1 is all Plug and Play. I am using an external power supply, and this product delivers it to all of my connected devices. The stability of every thing plugged into the USB Ports keeps everything connected just as it should. I recommend the Anker Product Line and this product in particular. SO, if you're in need of additional USB Ports, go with Anker.

It's a job but totally worth it

Size: 36 sqft

Pack a lunch when you tackle this project boys.. its a doozy!! Month in going great so far definetly did what I purchased it to do. 2000 chevy with two p3 10s every bass drop sounded like an old firebird with loose trunk bolts. Threw this on the back walls floor underneath the speaker and the doors.. all that energy is now in the cab with me instead of getting lost in rattling metal!! Love it!!! Left a few pieces outside after I was done rained like hell on them so water doesnt hurt this stuff at all or direct sunlight in south mississippi.. good stuff pick this up and make them systems thud instead of rattle!!! You wont regret it!! I didn't!!

Delivers a quieter ride

This works very well to put down road noise. The difference was immediate in my van. I was shocked it made such a difference.

Reasonably priced sound deadening

Size: 18 sqft

Easy to cut with a carpet knife. I used a heatgun to make it stickier and more moldable. The foil isn't so thick that you risk cutting yourself like some Dynamat variants.

Works for me

Sticky so don’t let it touch you or each other but it comes off and works fine.
