Just joined the forum. Glad to see all the activity. I’ve been using
Minimed insulin pumps for 32 years and overall it’s really helped
my control. I was excited about the new auto-mode technology in
the 670G and thought I would give it a try. I guess I need to vent
a bit about my experience in the hopes that Minimed will make some
changes and to inform others who are considering using the 670G.
Overall the clinical aspects have been good. My A1C went down by 0.5 (7.8 -> 7.3)
after using it for 3 mos.
Here are some of the downsides which are mostly user-experience-related.
The pump simply has too many alerts. For example, when you insert a new sensor
it takes a couple of minutes for it to “find” the sensor. It alerts you that it’s trying to
“find” the sensor. I don’t need to know that. Why not just alert me if you can’t
If it asks for a calibration and the value is high it warns you that it’s high. Duh. Then
when the calibration is finally set it warns you that…wait for it…it’s high. Double duh.
I think I know it’s high because I had to confirm the calibration value.
Here’s the fun one. If you calibrate and then want to bolus when it’s high it warns
you 3 times that it’s high instead of 2. Awesome.
If auto-mode needs a BG and the sensor needs a calibration they don’t seem to talk
to each other. You enter a calibration value but auto-mode still wants yet another
BG value. Sometimes it does not even register the BG and you have to wait 30 mins
and do it again. If it’s 2 am and you get woken every hour to enter another BG it
gets really annoying.
Vigorous exercise is tough to manage when in auto-mode. You have a few options if
you’re going to participate in vigorous exercise:
a) Use the “Temp Target” feature which sets the target at 150 instead of 120.
b) Exit auto mode and set a temp basal
For vigorous exercise, 150 is not nearly high enough. I’d like to set it at something closer
to 200 to prevent getting more insulin than I need. I end up eating all the time because
auto-mode keeps giving me more insulin. Crazy.
For the last month I have just given up on auto-mode and the sensor in general. I’m just
burned out with the amount of maintenance it requires.
Has anyone else just given up on 670g?
