Here’s a new failure mode for the G7. When I took the cap off the applicator I thought the sensor looked a little odd. It appeared glossy, whereas normally the adhesive makes it look more tacky. But whatever, new sensor day, so I blammed it on my tricep. It fell off immediately. Because there was no adhesive on it. (It did make a nice hole in my arm, though–thanks for that.) Poor quality picture below.

I reported this, obviously, but I guess just another thing to check new sensors for. Seems like a pretty huge QC oversight and reduces my confidence in the new manufacturing even further.
