  1. Jim Moreno

    Great! First set lasted about six months.

  2. Cindy Straub (verified owner)

    Battery barely lasted 4 months and I do not use the collar everyday. The original one I got with the system lasted a year

      Hello Cindy,

      I do apologize that the battery did not last as long as the first one did. We would love to speak to you about this issue, if you wanted to reach out to us at 1-800-305-6116. We do typically see a trend of the battery lasting anywhere from 2-6 months. It all depends on how many times the dog is testing the boundary on how long the battery last.

    I purchased this system 3 years ago for my two German Shepherds. The company has been very good at replacing the collars and batteries for damage. The batteries 7.5 volt has lasted 6 months before replacing them. I am very satisfied. Would greatly recommend this system. My dogs stay safe within my yard.

    The battery lasted about 20 days until the collar flashed. Never had that experience, and it usually lasts months (three-six months depending on how Beagle-ly the beagle is). So, why 5 stars? Got on the website chat, explained the problem, the rep looked it up, and a new battery is in the mail. Super easy. Every single time I’ve dealt with their customer service just reaffirms that I made a good call to go with this company.

    I cannot say enough about how good the customer service is at this company. I ordered the wrong battery for my dog’s collar. Contacted them, and they quickly sent out the correct one for me free of charge (no pun intended!) . I have never worked with a more responsive company.

    Let me tell you, if I still managed a company I would ask Darianne to come work for me! I had an issue with my collar battery and just emailed a little comment on their chat page and BOOM! Then next morning Darianne had written my an email stating she looked up my last order and is replacing it! If that’s not customer service and going above and beyond, I dont know what is. Hats off to EDF for hiring and keeping the best talent in the game out there!
