My MM723 had a pump failure last night. I went to bed with a glucose of 123 (corrected to 81) and woke up with a glucose of 197. I corrected and got it down to 166, then it just kept going up to a peak of 231. No basal delivery it seems. By then I had switched to my backup pump. This is my second failure of my 723 this month, and the third replacement in 15 months.
Maybe I am just unlucky?
