Functional
For backfilling saw cut concrete it works well. The packaging caused some but not many knots while working. Be sure to unroll before starting.

ok product
Foam is alright, it is just not strong and organized as expected or the description. Size is small, but it still can fill the gap and is ready for liquid to seal.

Used this product to block the light coming through the under cabinet lighting trim in a kitchen Remodel. Worked great, slid in between the trim and the cabinet.
