I got what I paid for, but I was hoping for more. Set of 2 dog potty house training doorbells were of poor quality. The strap was thin and hard. The length of the strap was short. I have a puppy, and the puppy would not be able to reach the bell. I would have had to join the 2 together to reach the ground. The loop did not come apart, but the strap was snapped to the loop and came off with very little pulling. It would cost me more to return these bells than they cost, so I'll eat the cost. Maybe the local animal shelter can do something with them.
