This collar is exactly what I was looking for to keep my dogs from escaping my yard. I spent weeks modifying my fence with jumping/climbing deterrent modifications and nothing was working. I also went to getting various types of electric dog collars, but they were not effective as it required me to see them escaping or notice that they have left, in order to correct them from escaping. The geofencing collars i did buy didn't have good applications, so using them were very clunky. My dogs were also chewing the collars off of each other so I couldn't keep a collar on them long term either.
My dog escaped and got into an altercation with my neighbors and I was at the point of giving up and having to evaluate what to do with my dogs. I noticed these collars and figured I would give it a shot. It turned out to be the best thing I could have done. The app was very easy to use and creating fences were easy. My dogs quickly learned the boundaries and stopped escaping. The collars are also pretty durable as my dogs haven't chewed them off of each other I have them on two 1 year old pit bull puppies. The tracking is also reasonable accurate it seems there are updates every couple of weeks improving the accuracy of the GPS.
Customer service is also great as well. I had one collar where the screw that connected the strap came off which resulted in my dog chewing the collar up, and customer service worked with me to get a replacement collar so that I could continue to use the product. This happened about 5 months after buying the collar. I am completely satisfied with the product and will spread the word to all who will listen to buy this product.
