AWFUL. The original LibreLink worked fine, but this new version with the Libre 2 sensor is maddening. If I have alarms set to ON, they go off all day telling me.... nothing, really, they just go off, and when I click the message on the phone it says "tap to open app." Why?? There's noting helpful when I open the app, no reason for the alarm. If I set alarms to OFF, I get alarms all day telling me that alarms are set to OFF.. I called the customer service line and the agent, although polite, did not seem to understand the issue, and merely walked me through resetting the alarms to OFF, then he told me to turn the phone off and back on again, which I did after ending the call. Of course I've had an alarm go off since then, so that was a waste of time. I'm a Type 2, not insulin dependent, I don't have lows and rarely have highs -- I could not get the agent to understand that I don't need alarms AT ALL but there is no way to shut them off. This has been designed by a committee of lawyers, not qualified developers. Maddening.
