I’ve had diabetes type 1 for 50 years this year (age 10 at diagnosis). Been through plenty with complications, including quadruple bypass 3 years ago, and other related and unrelated health issues. I’ve been using Medtronic insulin pumps since 1992, with a CGM and Enlite sensors currently, and am currently struggling to decide between the latest Medtronic 670g with Guardian 3 CGM sensors and Tandem T:Slim2 with DexCom G6 CGM. I have been reading lots of discouraging things about both systems and would appreciate the input of those who have experience with these devices.
