I know this is personal story but I bought this Land Air & Sea tracker because my brother was in the middle of fighting an active addiction. There where times he would be late coming home or go missing. One time I had a bad gut feeling and he didn't come home, I used the app and saw where he was, called 911 and saved his life from a Overdose! That was almost 2 years ago and he he now a year sober! If it wasn't for this tracker he wouldn't be alive. So this app has been a life saver for him. I'm so very grateful! He still doesn't know how I knew where he was? And I'll never tell because relapsing is real and I don't want him to know about it just yet. Thank you for your invention
