I own a PLB. I have never used it and hope I never need to. I bought it when I used to solo hike off-trail more than I do at present, but I am solo hiking almost always and my strong preference is for uncrowded trails with plenty of solitude, so it still makes sense for me. Also, my part of the country (Pacific NW) has very spotty or no cell coverage in national forests and wilderness areas where I tend to hike most.
