As a dog trainer I have helped install and train many different systems of wireless / boundary fence’s. I chose one that was best for my lifestyle / my dogs. I chose the completely wireless system as I live on property and have no fences. I have an older dog that is going blind and the ability to keep him from getting Lost (using the warning beeps that tell him to turn around) gives me peace of mind knowing he will always be close to home. Everything from the purchase to the advise for set up from this company was amazing! The dog line called me to let me know it was not in stock (even though I ordered late at night online) and then called me the very next day to tell me it would be in. They then called me to let me know they could express ship it (at no extra cost to me) so that I could have it faster! Amazing communication, great product and super fast delivery!
