## Customer Reviews

### ⭐⭐⭐⭐⭐ Great liner! Totally happy with it.
*by D***N on April 9, 2025*

First of all, when I tried to buy this, the message "This Does not fit your Gladiator" popped up. No idea why it said that, and I nearly didn't buy it, but it DOES fit my JT. Perfectly. This is an Amazon glitch, so they need to fix that.This liner looked great in the box, and it looks great installed. It is highly recommended that the top be taken off to put this on, but I did not take it off. As a result, I have a couple of small errors, but no one will ever notice them but me. It was difficult doing, and it required considerable strong words, but I hate taking the top off. If I had to do it again, I probably would take it off, just because I like perfection.It fits great, and it looks great. I got the white, and it's hardly noticeable. A couple of the backer foam strips were a bit to long, but I just trimmed them off.I just finished the project, and haven't driven it yet, but I anticipate a much reduced sound level. I applied it in the sun (and my top is black) and I could tell a huge difference in the heat coming through as I did each panel. That alone is worth the price.This adhesive is fantastic. It's instant adhesion, so don't let it fold back on itself. Buy this liner! You won't regret it.

### ⭐⭐⭐⭐⭐ Convinced
*by C***H on March 9, 2025*

OK, wasnt really sure what to really expect with this. Reviews were mixed. The installation is pretty simple. I did take the rear top off my Gladiator but I just rolled it into my bed cover and applied the BoomMat where directed that way. Made that part of the job really easy and it was the first time I had removed that part of the top since buying it a year ago.The install is easy overall and if anyone is unsure if this stuff actually reduces outside noise, take your Jeep through a touch-less carwash before and then after. You will definitely be able to tell the difference.I think it works great! Had one middle piece that wasnt quite cut right but a similar section of the front toos isnt even done in the instructions, so I just didn't put that one in the rear top either.All in all, happy. For this price, its worth it. We’ll see how it holds up to the weather impacts this summer.

### ⭐⭐⭐⭐ Overall a great buy!
*by L***T on July 14, 2025*

Perfect fitting, accurate cut parts, improved sound and temperature control. Needs to get better on the glue,after a few days needs to reinforce with 3m double tape to ensure in place in some corners.
