This keychain is perfect for parents concerned about their little ones wandering off. As my tests showed, it accurately tracks the location of the child wearing it. I love how easy it is to use and how it quickly syncs with my phone. The keychain is durable and can withstand a rough toddler. The only con is that the wristband may be too large for smaller toddlers but it easily fits on their ankle. Overall, it's a great investment for any parent with a toddler!
