## Description

Product description

Review: Adhesion isn't the greatest - So to start I have degreased anything that wouldn't promote adhesion and they still don't stick very good. I have also rolled over the product with a roller to promote better adhesion and it almost made it worse at times. I'm not sure how long this will so a further review in the future may be necessary.
Review: Solid quality, noticeably different. - Did the job as described, made a massive difference to the audible vibrations whilst driving and a nice addition to my driving experience. My forza speakers sound better too since. Can’t go wrong

## Features

- Package includes 9 sheets (49.5 mm x 38 mm each), total 18 sqft.

### ⭐⭐⭐ Adhesion isn't the greatest
*by M***S on 9 June 2024*

So to start I have degreased anything that wouldn't promote adhesion and they still don't stick very good. I have also rolled over the product with a roller to promote better adhesion and it almost made it worse at times. I'm not sure how long this will so a further review in the future may be necessary.

### ⭐⭐⭐⭐⭐ Solid quality, noticeably different.
*by J***F on 19 April 2026*

Did the job as described, made a massive difference to the audible vibrations whilst driving and a nice addition to my driving experience. My forza speakers sound better too since. Can’t go wrong

### ⭐⭐⭐⭐⭐ Gute Wirkung
*by A***E on 17 March 2026*

Da ich es benutze, um Vibrationen von HIFI Geräten zu minimieren, hatte ich erst Bedenken, ob 2 mm Stärke ausreichen. Aber das Material ist relativ schwer und hat eine sehr gute Wirkung gezeigt.
