I wish I had a db meter!
This product really seems to work. I wish I did a before and after db check. It really feels quieter. The material is very thick. It goes on easy, but follow the directions and take the top off for best results. I put it on with the top on and had some trouble over the speaker bar. Everything else was a breeze. No sagging or separation. The material looks nice but feels a bit rubbery. If I did it again I may opt for the leather feel option. Great product. I would definitely buy again.

Great product
LOVE how this reduces a bit of noise AND insulates the cabin. Dont expect the inside of your jeep to suddenly be as silent as a lexus with this---- but, it DOES absolutely deliver on sound deadening and increases your heating/cooling efficiency. Easy to install--I did mine without even flipping the hardtop over. Great stuff. Im curious about the spray they have. Anyone use that? Im thinking about filling the doors with it.

Poor quality
The product was advertised as a heat shield, but there was no aluminum on any pads. I had to purchase a separate heat shield and install it before fitting the pad. Additionally, the pad itself is very flimsy and falls well short of my expectations.

Works Great! And it DOES fit a 2021 Wrangler.
2021 4XE. Says it doesn't fit.. but it does. A little annoyed at the instal... the whole backside is sticky so it's troublesome sometimes to fit perfectly..but man it knocks out the sound well.

Looks great helps with lower noise level
Let’s start off with the install I did remove my top and flipped upside down for easier install. Clean top with alcohol so the material sticks well. I used my Apple watch to measure the db, without the liner and traveling 80mph it was reading 75db, with the liner on and traveling at the same speed it now reads 70db which is pretty good and also took the echo sound when talking to the passenger, the stereo sounds better also, I only have had this liner for the summer time you don’t need to keep your ac on high the cab cools down quickly and maintains cool temperatures, have done a road trip down the Baja and that was the true test all in all I’m happy with the looks and performance of the liner.

Boom Mat
Fit was good, instructions clear enough. Install went well, a couple small wrinkles. Love the grey color, matches jeep interior. We think there both heat reduction and sound damping.
