Thanks to my knowledge gained in practice as an Automotive expert, i can say with certainty that this toddler tracking bracelet is the perfect addition to any family's car accessories .Its simple to use, unobtrusive and has given me peace of mind while my little one explores. The keychain keeps the bracelet safe, too. The only con is the limited range, but it's enough for keeping tabs on a curious toddler in the car and nearby areas. Overall, it's a fantastic buy..
