Mixed feelings about this product
I do like this system but with that said I wish the collar was more durable. I have two German shepherds (2yrs old) that have bean on this fence since they were pups and it has bean a great training tool for them. On average my dogs break three of the in ground collars a year. They are active dogs. I also have the remote collars for both dogs, now for whatever reason they have took the abuse and never have needed to be replaced wish the in grounds were as tough. So now I'm faced with a choice do I get two more collars (because both have broke this week) or do I try another system?


We're terribly sorry to hear that you've had so many issues with the receiver collars breaking, Brandon! Please keep in mind that your collars are covered by a two-year warranty which will likely cover the problems you are experiencing. We'd love the opportunity to speak with you and see if we can discover what may be causing the collars to break and work towards a solution. We can be reached at the number 1-800-275-6797 for assistance.

keeps a 80 lb Plott hound in the yard
I've had this system for over 5 years and have not had a single issue with it. The battery lasts about 5-7 months depending on the brand, and wire installation was extremely simple. It has given our hound about 1.5 acres to roam at will. Have not experienced any issues with the collar other than the plastic strap wearing out, so I mounted the shock base to her leather collar and works fine. The battery compartment screws stay in, but i do check every week or so. Very satisfied with the system.

We have three acres of under ground fence, love the fact that our three labs can run around and feel safe that they won't get run over on the road. My problem is that they are always playing and they break the corners off the transmitters where the screws go thru. I would like to see a redesign on that part. I highly recommend your product to friends. I will be contacting you for a possible warranty.


Thank you for sharing your experience, Curt! We are sorry to hear that this has happened, but we are happy to hear that the system has worked well to keep your pups safe! Our Customer Care Team is here to gather more information as to what has caused the breaking at the corners, and our records indicate that you have reached out to us via Email. We appreciate all feedback and we are happy to offer any solutions possible!
