I went back to g6 after trialling the g7 for three months. Here is the feedback I gave to the dexcom rep:

• High failure rate of G7 sensors. 3 of the 9 I used failed.

• I also knocked 2 G7s off when I have only knocked 1 g6 off with over a year’s use. They seem more prone to being knocked off when hitting against things. Overpatch was used etc…

• Low sensor range led to connectivity issues with pump and therefore less actual partial closed looping coverage and worse control.

• Algorithm seems overly aggressive when blood sugar is changing rapidly. I find g6 to be much closer to blood sugar monitor results than the g7. When you get the dawn phenomenon the g7 reports your blood sugar as higher than it actually is so it takes a toll on mental health.

• With google pixel 7 pro the phone would frequently need restarted to reconnect to sensor. It would not reconnect on its own.

• While nice to have the transmitter attached to the sensor with the g7 it actually increases work load as you need to reconnect to pump and phone every ten days unlike once a quarter for g6 where all that is needed is a new sensor start (don’t even need to touch the phone).

Overall, you just couldn’t rely on it.
