You can pop the pump off on a moment's notice (there is a needle sticking out of the pod at the back, some other manufacturers use an umbillical that can be disconnected).
Totally agreed on the communications failure here, they all but blame the user for not noticing their error. That's not how a responsible medical device manufacturer should deal with this.
These wearable pumps, especially in combination with closed loop are a very interesting and important medical development that can improve quality of life for a huge number of people, but these sort of fuck-ups are really concerning. Inexcusable, especially because they have failed on multiple layers (code review, automated testing, acceptance testing, firmware development). Shocking, really and it makes me wonder wtf is going on at that company software development wise.
