I am curious why so many say it is too expensive, I got my charger wire and insulators for under $80. and I have it strung around my run and my garden, several strands. It is fairly easy to put up, and as a 1st step deterent I don't think it can be beat. I didnt buy posts, I zip tied the insulators to stuff taht was laready there and got creative in other places. Did I just get a good deal?
