My wife and her girlfriend carry one... didn't work last spring in Moab, UT. Has issues for sure. I think a Sat Phone is more of a realistic emergency aid.

I've used the older V1 and had problems. The spot connect is nice because you can send a text , I haven't had issues with it. It provides peace of mind to others.
I've used a spot2 a fair amount in the Missouri breaks area and in SW MT; it's always worked fine. With some of the other options that have recently come out I might not necessarily go that way if starting from scratch.
