i'd try one of the other pumps like tandem t-slim-x2 with a dexcom 6 sensor unless you're getting the guardian 4 sensors as the other one's need 2+ finger pricks per day or the sensor stops working and the pump drops out of loop the dexcom lasts 10 day's as well with the dexcom 7 planned to last 14 day in the future and is more accurate.
