They’ll never replace PLB/EPIRBs unless they bake in 406Mhz and 121.5Mhz communication. Satellite devices aren’t reliable enough for SAR. I’d even argue that they won’t replace Satellite Communicators - battery life isn’t good enough and the connection stability isn’t good enough

Same - I paid last year and it just expired, so I tried Brave Search, DDG and Startpage but they weren’t cutting it for me so I’ve just gone back to Kagi.

This may be a useful starting point. A few years old now but well researched and referenced.
