CICPAP GPS Wireless Dog Fence, Portable Custom and Circular Boundary System, 49-6500 FT Range, No Subscription, IP67 Waterproof Rechargeable Collar for 15-110 lb Dogs

Setup was easy, I just followed the directions. In the box you get the collar, the charging cord, a bunch of flags, the manual and a training guide. Something worth noting is you have to use a 5V 1A adapter to charge it or you could risk damaging it, and it doesn't come with one. So if you don't already have one you'll need to get one before you start. I've used it on both of our dogs a couple times today and so far it seems like it might do the trick. Our girl dog caught on right away. As soon as she heard the beep she stopped and wouldn't go past it. She actually looked down at the ground right where it beeped and after that she gave the whole perimeter a wide berth. Our boy dog couldn't really keep it on long because it started storming. He's a little nervous with it right now so it's too early to know if there will be much progress with him. So far one dog got it the first time and the other one just needs more time.
