### ⭐⭐⭐⭐⭐ Review
*by C***0 on 1 September 2022*

There's no better tape period, this is the real deal. Quality product, pricy, but worth every penny. I had multiple air bleed connecting seams, did my entire basement ductwork with 100 feet and some left over to do a few more seams. Get some little scissors to cut it with, makes life easier. The utility blade crumples the corners a bit, which makes it trickier to get the backing off. Hope this helps!
