I use an older InReach when I am touring solo in remote (no cell) areas to make my wife happy. Luckily, I have not had to use it for an emergency. PROS: I like how others can get (mostly) real-time location on me and the tracking is very accurate (probably within 3 meters), you can send messages back and forth (about 10 minute round trip though), and the battery life is very good. The CONS are it is one more thing to deal with and as mentioned, messages can take 10+ minutes to do round trip, i.e., I send and it is 10+ minutes before I get their response even if they immediately replied.
