I was so pleased with this Fence. I was so exhausted trying to contain my dog. I would hate to leave the house, knowing that when I returned the dog would have escaped. An Animal Control Officer recommended I try Invisible Fence Brand. I contacted their office and they were able to come out that day. They walked my property with me, helped me to design the fence, installed the fence, trained my dog and they were done in under 3 hours! Amazing!!! The Technician and Pet Consultant were so professional and helpful. I wish I had thought of this years ago. I even found out that it is lifetime guaranteed and if I move I can take it with me. I am done with my fence problems, forever!
