We have been using Life 360 for several years and although it is far from ideal, it is by far better than other similar services that we used before. My friends and I use it when we go to Airventure in Oshkosh WI every year where there are 20 or 30 thousand people in a 300 acre area and have little or no problem in locating each other to within 50 to 100 feet. My wife misplaced her phone and Life 360 found it in our grandaughter's car which was parked outside our daughter's house where she had mistakenly left it. One of my friends likes to travel and I routinely follow him to places live Scandinavia, Taiwan, and other Asian and European sites where it seems to work just as well as in the US. Yes, we have had some of the problems described by others, but feel that its usefulness far outweighs its shortcomings! - HD, Georgia
