A very worthwhile investment
This is a fantastic device. I bought it after my precious Golden decided to wander off. She doesn’t know she has it on because it’s very light. The battery is lasting more than a week even with daily two mile walks. The battery is conserved when she is home. I love the app on my iPhone. The tracking is accurate especially in Live mode. I have upgraded to premier so I can keep track of her activity for a whole year and my family can track her too. Definitely worth $8 a month! Highly recommended.
