Sensor Failure

 Put a new sensor in this morning and it never did start working right.

Here’s a picture:

So I called Dexcom tech support, hooked up the sensor and sent them the data.  They agreed it was bad, and are sending a new sensor and a return kit.  That’s good, because that gives me a second “emergency” sensor.  I love the way they package the single sensors, as I can just tuck the box in my emergency kit.

That’s the first time I’ve had a sensor start out bad, but I am thinking it is the second sensor in the same lot. 

So far, I’m on my third box of 4, I think, and I’ve had three sensors fail. One was a 3 day sensor and I just put it in wrong.  One failed in the middle, I thought caused by downloading data, and then this one.
