Review: Very good wire - I installed this wire two years ago to keep my golden doodle out of the garden and pond area, which are on opposite ends of the yard. I wanted for her to be able to run in between the two areas. This wire is easily installed, and when it is twisted together it cancels out the signal so that one boxed in area on one end of the yard can be connected to another area on the other end of the yard, while allowing the dog to run without getting a shock. All of this wiring then runs into one control box for power. My dog has learned very quickly to stay out of those two areas. The collar shock is adjustable depending on the size or tolerance of your dog. This is really good wire and is easy to run.
Review: Awesome! - We had an invisible fence at our other home and I was so happy we got this for our current home. The dogs are happy to have freedom and not getting tangled in everything. Husband and I easily installed the fence. We got 2 collars. All works as expected and it's so nice to work outside and know the dogs will stay in the yard.
