I’m very satisfied with my Tracker Card. It’s thin enough to where I forget it’s in my wallet, has pin point Google map location, an audible beeping sound to further locate it, and charges pretty easily and quickly. Plus, if you press the button on the card, my phone will ring, so it helps if I can’t find my phone if I lose my phone. My only issue with it is that sometimes the button on the Tracker Card will press down and ring my phone while I’m sitting on it and driving, which presents a distraction during driving. Otherwise, it’s a very nice tool.
