I bought 3 of these and put one in my wallet, my wifes purse and dog collar. I'm able to easily find them all easily whenever I check my phone! If I ever lose my wallet I'm confident I'll be able to get it back!
It works awesome, I'm actually so happy with my purchase. I put one in each of my childrens bookbags :)
As a self proclaimed helicopter parent this is a dream come true! I know where ever my kids are, knowing they are safe at all times!
