Highly recommend.
I would highly recommend this tracker. I got it for my mum and put it on her keys which fortunately she always took with her. Not only was I able to quickly locate her, the history which pinpoints routes and time stamps on a map provided evidence for social work and medics that my mum was becoming increasingly vulnerable. She has recently gone into care but this tracker filled the gap before that happened and helped keep my mum safe. The customer service is excellent and I got tech support early on when the app was a bit glitchy. I would recommend using it with an air tag. Once you locate the person, the air tag is a bit more accurate with exact locations.
