KOFOHON In-Ground Electronic Dog Fence System Wired Underground Electric Pet Containmen Kit Rechargeable and IP66 Waterproof Beeper/Shock Training Modes for 1/2 Small Medium Large Dogs/700FT Wire

Seems to work ok..but we had to figure some things out for ourselves because the instruction manual left MUCH out. I still don't know how to power on the collar correctly. I just keep hitting the button. I will hear a short beep, a long beep, a flash of a green light , a flash of a red light. Still not sure what's going on but we just hit it until the collar reacts to the boundary wire. Which takes up more time than I would like since I have to go test the collar Everytime I let my dog out to make sure it is powered on properly and responding. Other than that, it works well. Keeps the dog in the boundary.

I actually returned this I did not like it I thought it was something for my fence to keep my dogs in and it was more of a shock collar

This is a wast of money it lasted 3 months I bought a collar control replacement and it didn't work the batteries got never charged and the transmitter broke on it's on dont buy this product
