## Customer Reviews

### ⭐⭐⭐⭐⭐ Very flexible and stays where you put it.
*by L***H on March 8, 2025*

This worked great for what I needed to stuff in the saw groove in my new concrete then I chalk it .

### ⭐⭐⭐⭐⭐ Works as advertised.
*by J***B on January 14, 2025*

Basically if you have larger gaps that need to be caulked; add this to it and it will reduce the gap / reduce amount of caulk being applied and ultimately nicer finish.

### ⭐⭐⭐⭐⭐ Used in the gap between my french doors
*by N***N on January 19, 2025*

Very easy to cut and place in between my two french doors. Helps keep any cold air that gets by the doors weatherstripping out of the house.
