I finally received a Freestyle Libre 2 continuous glucose monitor (CGM)! Yay! Got it out of the box, set it up, applied a sensor only to find out the reader could not communicate with the sensor. After looking at the logs on the reader, I discovered it was not a new reader, but one that had been sent out twice before I received it. It's fukkin' defective. Then, the wife unit commented about how the clear vinyl overlay for the screen didn't look right - yeah, it had been removed, then reapplied at least once.
So, Abbott, the maker, is going to send out a replacement reader and a replacement sensor, since a new reader can't communicate with a sensor that's been activated by another reader. It's just the fukkin' hassle to having to send shit back and deal with setting up a new reader, applying a new sensor, etc., etc.
BTW, did I mention just how tenaciously that sensor was stuck to my arm? Thought I needed a pair of pliers and a pry bar for a few minutes.
