Featured review
This review was chosen algorithmically as the most valued customer feedback.

I have aTslim pump which also uses my Dexcom G7 sensors. The readings on my pump are different than the readings on the Dexcom G7 App. Ridiculous, even after calibration. Why? I am told by Dexcom their app is perfect. But it shows a lower reading than my pump when at 70 or less.

The app, once it starts alarming there is no way to acknowledge the alarm so that it will not continue while you are treating you low. This is ridiculous also.

Recommendation: G6 may be a better solution or another supplier of the CGM
