The product arrived as promised. We installed it with the wire above ground so we could test it. Once we were confident that it was working, we buried the wire in places where it could be damaged. The process to bury it was simple if a bit tedious. We pushed a flat edged shovel into the ground and then just pushed the wire into the sliced ground with our hands. In the two months since it was installed, the wire stayed put and was never damaged by lawnmowers or other vehicles. In order to complete a circle around about 3/4 acre, we needed to use additional wire.Initially, we did not twist the wire tightly enough to keep it from shocking near the control box, once we figured that out and got the wire near the back door high enough so it would not shock the dog when he came to the door, the system was completed operational. That was the easy part. Training our three year old rescued border collie took a bit of patience. He was new to us so part of the challenge was simply that we were figuring out how he learned while trying to train him to use the fence. It took 3-4 weeks to get to the point where we were confident that he would not run right through it. Part of the issue was that I was hesitant to turn up the shock to a higher level. Once I did, it was much easier to get his attention. It does take consistency and patience. We kept walking him around the perimeter and showing him where it was safe to play. In the end, he loves to go out and explore in the yard.This was a great solution. We wanted to fence a large area and cross the lawn. There was not a good option for a physical fence as we need to be able to drive to the back field periodically and needed to and cross the lawn. This fence worked perfectly.
