Within three days, both of our dogs had calloused bloody skin on the bottom of your neck

The guardian system worked with training for about 6 months. My dogs collar broke and repeatedly shocked my dog over and over while I was at work. Thankfully my neighbor was home when it happened ran over and got the collar off and rescued him. Do not recommend. Experience was traumatic.

So far, we are loving these. Where my halo collar was not strong enough for one of my three dogs she actually listens to this one. My only complaint would be that the boundary has to be so far away from a building to be set and it is not as easy as halo to set up your fence fences. They should compare and perhaps do a better job with that. Also, Halo has the option of having keep away areas inside or out with small beacons. I really loved that and miss it.

This GPS fence accomplishes what I need it to do, and is just a few features away from doing everything I want it to do. It was relatively easy to set up, with very few steps to the process. Drawing the fence and adjusting it is simple. The app is perhaps missing a bit of functionality, but nothing that impacts the base use of the collar. From easiest to hardest to implement: 1) indicate clearly in the app when the last time the collar’s state was updated. 2) Allow me to choose a tradeoff between accuracy and battery life. This collar would be massively improved if the battery lasted 12-24 more hours. 3) Allow the collar to update its state through my phone when I’m close enough to the collar. 4) Allow me to issue beep, vibrate, and static corrections directly from the phone (or a separately sold handheld unit). 5) Swappable batteries for the collar.
