Dee @HighHopes, if you can maintain relatively good glucose management with your current 670G, it may be worth your while waiting for completion of the 780G trials and then make your decision.
Medtronic has said that it has addressed many of the user gripes inherent in its present flagship, the MiniMed 670G. Additionally, if Medtronic is able to integrate the apparently awesome claim of Klue, a recent Medtronic acquisition, the 780G could become the first completely “closed-loop” system. My assessment also assumes improved reliability of the Guardian sensor.
Medtronic often allows upgrade incentive for current users of its “in-warranty” devices.
