Mine works fantastic.
I have 2 beagles out on our 3 acres.
Ran the wire around the entire perimeter, buried the line under the entrance of our driveway when the driveway got re-gravelled.
Zero complaints, works perfectly and gives us fantastic piece of mind. Open the back door and let them explore the woods. It’s 3 acres of woods, with a nice area cleared for our house.
