Did it's job well.
I had to fill in gaps between the pool coping and the pavers. This worked very nicely. Need a lot of caulk for deep holes. This really helped minimize that and was easy to push in.

Not sturdy
Received in a roll that was bent so bad in about 4 places so I couldn’t use it to sill anything. I ended up just throwing it away. Don’t waste your money. Take the time to find something better.
