Works pretty well in my area, though not so much wherever there’s a ridge and no node to help propagate the network over it. There’s a few slivers of town without coverage, but there’s a very large, multistate group of enthusiasts expanding the infrastructure.
Some have also left Meshtastic entirely, in favor of Meshcore. I might try it on my spare T Deck just to see. But Meshtastic is fun, especially if you enjoy the potential for tinkering with things. I had a blast going through the thread of putting MT on some Chatter2.0s, along with some mods to the boards. Now they’re like little mesh Nokias, ringtones and all!
