Great investment, works perfectly
My husband is the master at loosing keys, just this year he's lost 2 sets of car keys. Got him a twin set of tags for fathers day. He was doubtful they'd work but on the weekend he lost the keys and found em in minutes, they'd pinned it down to within 3 metres and he traced the sound. No more panic of everyone stop what you're doing and help search for keys!!
We have a puppy that's good at escaping, considering tagging her next 😁🐶
