I'd want see what some serious hackers can do with it first. It wouldn't surprise me if it were a deepstate ruse to get the gullible to buy it believing the advertising only to monitor everything they say, do, go, etc. The fact that it works on other networks is a problem. If they said it was their own encrypted network that bypasses all existing towers and network switches, that would be something to look at. That is basically military encryption and even that isn't without problems.
