I received the "sensor is going to expire" icon this morning. So, I ended the sensor and restarted it.
The bandage part of the sensor seems to be in good shape -- in fact better than the last sensor.
The sensor has been extremely accurate. I've drastically cut down on finger sticks this week, and have been dosing based on the receiver. It's working well. I haven't gone low all week and the few times I've gone high, I knew why.
