Sadly I lost this trackable on the way to a geocache I remembered putting it in my pocket and when I got there I wanted to place it inside and it wasn't in my pocket. This thing is so tiny I hope it lasts. I spent more time looking for the trackable than I did looking for the geocache itself. I did find it and I placed it in the geocache I had lost it at so I wouldn't risk losing it again. No more tiny trackable moving for me. That was scary to think that I might have been the person to lose someone's trackable.
