Great for threshold gaps
Had a small gap in my front door threshold after one of our animals ripped up the material that was originally in the gap.After reading many reviews for this product, gave it a shot. It was just what I needed! Super easy to use: measure, cut, install. Fits perfectly in the gap. No need to worry about dirt, bugs, and other debris getting in the gap.Great value too, as the 20ft bag was only about $3.00, with plenty left over if I need to replace it again.Highly recommend.

Good product for driveway cracks. Description says pack of 2 but I only get 1.
It works and is useful. Again, I don't understand why it says pack of 2 when I only get 1.

nic backer rod
A good filler for wider spaces between two panels that saves caullk/ adnesive/ sealiant. I am using this backer in some spaces between sheetrock and flooring to liquid proof them. Also good to keep critters out.

Good product
Works well. I bought it to fill in gaps in my driveway. For the smaller cracks I cut the width of it. It is durable and a good price.
