### ⭐⭐⭐⭐⭐ As advertised

Easy to install and form.

### ⭐ Poor quality
*by A***R on May 15, 2024*

The first one I received was returned due to the same problem, the metal heat barrier separated from the fiberglass backing. The picture posted in this review is of the new one I received and has the same issue, I'll be gluing it back, not sure how long this will last. Very poor quality!!
