I've had the system for 4 days now, and all of the other reviewers are correct. The alarms are the most absurd thing I've ever seen. I'm sure lawyers are the reason for it, but it's ridiculous. I'm type 2, so a low glucose event isn't in my cards. But this app has an alarm, that can't be controlled, or turned off, with that screeches whether you are asleep, or in court, at a kids performance, telling everyone nearby that you are an inconsiderate jerk who won't silence your phone. Absurd.
