I would like to take a moment to say how much I love this collar! Right from the start, opening up the package, it matched the color of my collar that I ordered. I loved that. The set up was fairly easy and the app is easy to use. I have a livestock guardian dog that stays outside all day with my chickens and goats. The collar is very durable as well, my dog has put it through the test. This collar provides me peace of mind knowing my dog is in the areas I set up as his safe zones. While I am at work I am able to track him and make sure he is safe. I have had other GPS collars in the past and what sets the Averia collar apart from competitors is their customer service and support. This is just as important to me as it is to have a tracking device on my dog. If something happens to your tracking collar on your dog you want fast action support from the company, it could me life or death for your dog. Averia collar has provided this for me.
