I’ve had this unit for about 2/3 years now and I’m coming back to review the product and how it’s changed our life of being dog parents. I have golden doodles and poodles. I’ve also had a GSD on this fence as well. I initially got this fence because it was wireless and my dogs kept traveling all around my residence. I don’t like my animals going onto others property whenever they please. When I first purchased the product I put the flags up immediately then walked each dog along the perimeter of the fence. It only took 2 days max for all of my dogs to learn their perimeter. I currently have 4 on this on device. The main until stays in my kitchen and they have a perimeter that allows them to go about 5 ft from the edge of my yard and all around in a circular shape around my property. I do have my perimeter set on the shortest setting but that is way more then they need. They also can go inside their building as long as they stay within the perimeter of the fence. They have learnt their boundaries and had a few shocks to understand it completely but if I walk outside of the perimeter I always tell them to stay to remind them and they do wonderful and will sit and wait for me to return into the safe zone. This unit has been amazing and I have no issues or negative to say about it. It’s worth the cost and being wireless is the big bonus. Just make sure to pay attention to the collars lights and you won’t have any issues. My dogs can go without collars and still remain inside the safe zone. I’ve recommended the stay and play to all of my dog friends. It really is a lifesaver because my dogs aren’t chained and they come in the house and go through the doggy door as they want throughout the day. I no longer have to worry about where they are or what they may be in. Don’t hesitate but this fence.

105 feet from the box is the maximum radius. I would need so many boxes to link together for the dogs to have a decent area to roam.
