PetSafeStay & Play Wireless Pet Fence with Replaceable Battery Collar - Circular Boundary Secures up to 3/4 Acre, No-Dig Portable Electric Fence, for Dogs 5 lb & Up, from Parent INVISIBLE FENCE BRAND

We have had our main Pet Safe unit and collar for a couple of years and this system is amazing! Our dogs collar just recently snapped and ordered this replacement. It set up seamlessly with our current unit. The batteries last us almost a full month of daily use. We'll worth the investment!

This wireless fence system is very easy to install and works very well for our high energy dog. Our property is not fenced, but is essentially flat so we were able to achieve a consistent boundary perimeter. We bought a package of 100 yellow plastic flags and are using them rather than the 50 flags included with the system, as we needed that to achieve an even ten feet between flags. We followed the training instructions exactly as described, and by the second day, our dog would not go so far as to be within the buzzing-alert range. The first 4 days of training, I kept him on the leash and walked in all directions towards the boundary, multiple times each day. He consistently initiated “putting on the brakes” as we approached the boundary, so I would lavishly praise and reward him. Days 5 - 8, I still kept him on the leash and added distractions. He completely restrained himself and would not pursue the toys or people approaching until they were far enough within the boundary for the dog’s comfort. Days 9 - 30 (we’re currently on day 24), we moved to unleashed supervision and play. We’ve successfully played fetch an unlimited number of times every day and played endlessly with the kids. If the ball happened to land too close to the flags, he would not go get it. Or, if the kids left the boundary, he would not follow them through it. However, one afternoon around day 17, a cat was meandering within the boundary and the dog saw it from inside and went nuts. When I let him out the door, he chased the cat through the boundary. He got alerted and zapped but didn’t stop until he was a hundred yards away. Then he came to a complete stop and walked back to me. We walked inside the boundary and I praised him for coming back within safety. Following that, I walked the boundary with him on leash again and he would not go anywhere near the edges. After that we went back to unleashed play and supervision, and he has not chased anything through the boundary again. Two days ago, as we went outside, we surprised the cat, who ran away quickly. My dog gave chase for about 6 feet, then stopped well within the boundary and just turned around and looked at me. I praised him lavishly again. I’m very optimistic that this will be a reliable, long term solution. I recommend it.

This product arrived promptly, intact, and ready to put to work. The instructions were clear and complete. The collar fit our cat, and he quickly learned not to transgress the boundaries indicated by the beeping noise. There is (of course) limited range (about 100 feet in any direction) and there are some obstacles (like metal) that may interfere with the signal, but we have found it very effective and a good sized area for our two cats.

UPDATE: Although I am still pleased with the overall concept of this product, I am becoming increasingmy frustrated with the power cord. FOR this to be not the best location possible for my dogs I needed to have it plugged into an extension cord. FOR whatever reason, and after trying multiple cords, the unit continuously and randomly loses power. If this happens while I'm at work and the "no power alert" is no longer sounding, the unit is useless. I will be reaching out to Amazon & Pet Safe for a response.Love, love, love this! Just what I was looking for. We have a large yard that would be difficult to fence in but needed a way to contain two newly adopted yellow labs. It took a bit to figure out just where to place the base to keep them away from the neighbors yard on one side but give them enough space to join us at the pool on the other. I would give this five stars if the base could be located outside. I currently have it in the garage as that's the location that gives the best radius. I was slightly concerned with the volume of the tone being so low, I've only ever needed to use tone - they respond very well! After using this for approximately six weeks I'm thinking the volume is fine, I'd still be happier with a louder tone though. I'd also like to see more choices in collar color. My labs look almost identical and when out in the yard it's tough to call them by their correct names without having those helpful hints! A choice of black or red just doesn't do it for me!The training materials were helpful but honestly, it only took me three days to show them their boundaries before I was comfortable with letting them out off leash. They respond very well and learned quickly. I'm still paying close attention as we do have "wildlife" all around but they're doing excellent - the didn't chase the squirrel that ran across the driveway out of their boundary so it's all good!All in all, very pleased with this unit and would recommend it.

I so wanted this wireless dog fence to work. It came in the original box but the components were basically thrown into the box. I did buy the used version but it was rated as good as new with battery in original box.. First the battery was dead, I could not even test it to make sure it worked when it arrived. Because I work pretty much sun up until after dark I had to wait until the next weekend to buy new specialty batteries and have time to test and install I was without a needed fence for a week. After getting the battery, setting the boundaries and making sure the lights and collar came on, I headed outside with the flags. It was difficult to locate the “fence”. After getting the first alert I followed the arc of the path and could not find another alert. I went back to the original flag and then could not find the original alert. I did this over and over. Ever time I would find a random alert in the yard I would market with a flag and then go back to find no alert again. It was awful and time consuming. There was no way I could trust such an iffy consistency with the safety of my dog. I packed it up and returned it. I will search for another system. Very disappointed.
