I wasn't sure at first what to think about this fence but ive had it for 2 months now and it really does work. My dog is the terror of the neighborhood by no exaggeration chasing cars, picking on small dogs, chasing chickens etc he is a redbone coon hound and everyone around knows it lol He was getting death threats before I had to zipline him for the winter.. I had to do something and I could not leave him on the zipline forever so I got this. It was not easy to install it was tedious and hard work. I buried three quarters and ran some along fences were available. I installed 2 rolls of wire. I even hooked up the electric part myself!! My dog got zapped ONE time that first day and was pretty freaked out he sat on the porch for days thinking it was the only safe spot buuuut then he found his area and tho he ran through a few time the first month he has not got out but just a few times and he easily went back to his area. People thought I got rid of him bc hes been in his own yard! Its pretty awesome.. hes happy I'm happy everyone is happy. worth the money if you have little options and love your pet.
