Review on Enhanced PetSafe PIF00-12917 Stay and Play Wireless Dog Fence System for Dual Dogs by Tim Loya

This fence works great with our two dogs. Both train very quickly and stay away from limits. (We have it on setting 3.) We're not on flat terrain, but it seems to be handling it pretty well, perhaps getting more distance on descents and not as far on a climb. We also have a lot of trees and we don't think they are a problem. I will say that on our land this is not a very perfect circle and it may be due to the slope and trees but it works to keep the dogs in our territory and we don't care too much about how perfect the circle is. We have 1.33 acres and on max settings it covers just enough to give the dogs enough room to run without the curbs being off the road.
