had it for 6 months it keeps my dog in yard . don't have any complaints it beats paying 1600.00 to 2000.00 for a dog fence company to do the job. I had to rent a wire burying trencher and bought 1000' of 14 awg wire. Maybe overkill on wire size but I don't want to have to fix the system when the cheap wire gets broken. even if the power supply fails prematurely I just have to buy another one of any brand I would recommend the DIY to install does take quite a bit hard work to get it done but worth it. You could use a shovel but I buried 800' of wire.
