easy set up, easy to use and at this price point that is what I expected, so far it's working great and we are very happy with the results, have tried a lot of others with no success, this is the winning one!!!

Gps good but only for bigger yards
I like the gps function and it's easy to set but the minimum radius is too much for an average yard.

Truly Wireless
I like the it has a warranty. I like that it’s water resistance so it can be worn in the rain or snow. The best feature that I like is that if my dog should leave the boundary that the collar will automatically shut off after 3 cycles as to not hurt her, when she returns it will start working again. This is truly a wireless fence, I love that I don’t need to bury any wires or need any transmitter, operates by GPS signal.

Zapped my dog inside the perimeter
We got 2 of these for our dogs and have been using them for about a week. Setting the perimeter was not intuitive, but using the manual, we were successful, and tested them each day before putting them on the dogs. However, yesterday, one of my dog was sitting out in the yard, well within the perimeter (after having set it more than an hour ago) and all of a sudden, the collar began to make the audible beep. He lept up and ran for our shed (where he likes to shelter, also within the perimeter) and then we heard him yelping because he was being shocked. We ran to get it off him. Now the shed has a metal roof, so it's quite possible that it was the reason it started to shock him, but there was no reason for it to even start beeping while he was in the yard. We returned both units as we find this unreliable behavior of the device. I can't even image what would have happened if we weren't home :(

Your dog will enjoy having free roaming time :)
I bought this for my 3 year old Rottweiler, he would always run away from me but after doing three training lessons with him he gets the point that if he walks away he gets zapped. My dog likes swimming in the pond and that’s was a perfect opportunity for me to test out if it’s waterproof, and Yes it is waterproof still works like new.I whish it had a preset so that I wouldn’t have to key in the radius always. That’s my only complain.

Great works
It is more effective than the invisible fence system I have used! Follow the seller’s facebook video tutorial, easy to install.

I wish I would have listened
I wish I had taken the reviews seriously. I ordered two of these for our dogs. The one collar came without any instructions and had to wait for the second collar to arrive. There was no way to know how to calibrate it without directions. The other horrible thing is that once the collars start being tested a few times, even in training, they then wouldn't shut off and kept punishing our dogs. They'd run under an object to try to get away from it, and even then, it wouldn't always shut off. We tried them for three nice days and it was no good.
