Review on 🔌 OptimalSearch Boundary Wire: Durable 16 Gauge and 20 Gauge Options for Electric Dog and Cat Containment Fences - 500 FT & 150 FT Lengths from the Parent Company behind the INVISIBLE FENCE Brand by John Destruction

I was skeptical and didn't really think it would work. After installing the boundary wire, we had trouble adjusting the collar. The first step instructs you to "remove the battery". This made the next steps completely pointless. However, I contacted support and got the instructions I needed. The support rep agreed that the issue is with management and hopefully they will fix it. Now to the effectiveness of the boundary wire. It only took my German Shepherd Dog 3 days to start respecting boundaries. Once she "jumped" over the "fence" while chasing a squirrel. She received a correction, and then was afraid to return to the yard. I solved the problem by driving the van out of the yard and she came back with the van. (She doesn't get a shock in the car). Now it's a pleasure to let her off the leash and be outside (she has an acre or more to walk).
