Just what we needed to plug the hole on our hot tub.

Needed a filler cap for the pool step rail. Does the job! Lasted all summer. No cracks. Great value.

For a hole in a plastic owl I had. Not a true fault, but I wish I could have bought only 2.

Amazon needs to fix this description, because for the color it says both grey and black, and I didn't notice this when I ordered and assumed black, but what I got was a set of grey plugs/seals. Ultimately not a big deal for my purposes, as long as it plugged the hole effectively. I had 1.75" hole in a kitchen cabinet that needed plugging, and it dropped in snuggly.

This plug works well to cover the seat post receivers in the floor of a bass boat. They are easily removed and fit snugly enough to keep water and debris out of the holes. They are not water proof, but keep the majority of water out.

It fell through the hole it was suppose to plug. It doesn't have enough overhand on the top. I wound up making my own plug.
