Here’s a perfect use case.
Yesterday, we went Christmas shopping, as did nearly everyone else, so parking was fun. Instead, while the others went into the stores (running around just getting 1 or 2 things from multiple stores), I’d search for a parking spot. When they were done, they’d ping me over the mesh and I’d pick them up outside each store. The Mesh units worked like a charm, even through a couple block walls and a car door at distances less than 800 feet, matching cellular SMS service.
