I changed from MM640G to MDI 6 months after start, you can read about it here
My problems were more sensor related, but i agree on the more difficult handling. I loved the easy bolus before and now it’s just not easy anymore.
I was in camp last summer, and we had to call Medtronic to send in replacement pumps 4! times!! from screens breaking to motors not working, we had the lot. that poor lady on the phone recognized me at the end and apologized to all lengths. We never had so many pumps break in a two week camp with 40 kids ever before.
Sad record tbh.
however, i must also say we were also soooo thankful for the auto hypo regulation, it saved us a few times and was godsent. i think while the new pump is not very childproof (they just need stronger cases) i can also imagine that this is the pump many d-parents (and other PWD) have waited for for ages, if the hypo suspend works well it is just an awesome piece of technology.
