I have a breastcollar that lost it's snap at the end of the strap that connects to the cinch ring. I had been running the cinch through the loop and annoyed me, but I was still not fed up enough to buy a whole new breast collar. I saw this and bought a few of them and it was very easy to attach. I was worried about the screw coming loose, but it is engineered to stay tight and it hasn't come off or loosened at all. I'm very happy with this product :)
