One small thing to add to Dennis last post. Minimed 780 is the same pump as the minimed 770 but with a software upgrade. So it will use the same bulky cartridge as the 670 and 770 .
ive had the autosoft. never liked it or the idea of being connected to a tube. so i switched back to shots. then one day i came across omnipod. they were new at the time but it was cordless and something so cool. I just had to get it. when I did, it was a LIFE CHANGER. Worth every penny and im more efficient with my diabetes.
