txdon,
We have been using Whistle brand for 3-4 years. They are a good company to work with. We have a Jack Russel that formally as a pup, was an off the leash guy. But he had a hard fall and the vet said to he him inactive for a month. When the time was up, he became very independent!. He would come in when HE wanted to.
So we got the Whistle tracker. It's very good. We always know where he is. It doesn't bring him in, but at least we know where to look. We are at the end of a 1 mile private road so normally roaming is fine. But as night falls, he is Coyote bait for sure. Our trick to get him in is to head to the mail box, 1 mile up the road. He loves to watch for squires from the dash. Then we drive in to the garage and close the door.
The apps works good 99% of the time. I don't think you get 5 days of active tracking but We have a routine where we charge it in the evening when we set up the coffee machine before bed.
