Hi James,
I started the 780G on the 7th of January. Ive had a few issues with the guardian 3 cgm, but the pump itself & the automode function is absolutely amazing. Time in range is typically 90-95% every 24hrs. A1C was 83 before starting the pump & Carelink is predicting a A1C of 49 (6.7%). Auto mode while asleep is outstanding, since starting ive never been out of range during the night as the pump micro basal & gives auto corective bolus every 5 minutes to keep sugars in range. I can even have a takeaway on a weekend & not worry, I give a rough bolus & then if I have under estimated the pump will correct if I start to go high. Make the switch, you'll love it
