I really do not want to talk bad about the Medtronic 670g because it was working so well for me. For about three months my BGs were so great. Auto mode was the best thing to ever happen to me. I was finally able to control my diabetes for the first time ever!
Note I said it WAS working so well.
For the past few weeks I have had nothing but headaches, frustration, and at times total rage over this machine.
Sensors- At first the sensors were super accurate but I had trouble with them failing before their full week was up, no big deal but a bit annoying. But then the latest three sensors I put in have been super inaccurate. 3 sensors from two different boxes. I mean super inaccurate! They rarely were more accurate than 30 points below my actual BG and most often were upwards of 60 points below! I kept each of them in for the entire week, hoping they’d work out their own issue, but they never did and I got all kinds of alarms and calibration alerts and continually got kicked out of auto mode.
Now, we all know how important it is for our CGM to be accurate. Beyond the usual importance it’s also important for accuracy with the 670g in order to stay in Auto mode and get the proper amount of basal insulin! And I personally NEED my auto mode because it’s the only tool I’ve ever had that actually makes it possible for me to keep my BG in line!
Loop traps- For the past several weeks I have been fighting (and losing) the loop trap battle. With the 670g a loop trap is when you calibrate and then the machine immediately requires a BG to be entered for auto mode. OK, no problem, wait a few minutes then enter BG. Then the machine immediately wants another BG for auto mode! Then another! Then it wants another calibration! GAHHH! Stuck in a loop!
It’s annoying as hell! Just imagine having an alarm -Beep! Beep! Beep!- going off repeatedly all ■■■■■■■ day (and night)! Not to mention the constant finger pokes for the required BG checks for this loop trap (yes, I can and often do just manually enter a number similar to the last check)!
The only 2 ways I’ve found I can deal with it is to 1) wait at least 15 minutes between BG entries (in order to let the machine “catch up”). This sometimes helps to prevent or stop the loop… for a few hours, then it starts up again. 2) Disable my precious Auto mode for 8 hours then go back in (I usually disable at night so I don’t get bugged by the beeping if it gets stuck in the loop!). This often stops the loop trap for half a day or so…then it all starts up again!
I find myself going insane from all of this stupidness! I once got so pissed at the constant beeps and the frustration of not being able to stay in auto mode that I actually punched a brick wall. That was better than what I really wanted to do which was throw my pump at that brick wall!
The past two weeks my BGs have been running higher again…
A few times I’ve just broke down and sobbed. I had finally found something that actually worked. My BGs were so good. I rarely went above 170 or below 74. Then it was all so cruelly torn from me.
I’m not doing anything wrong. I follow the training, the manuals. I don’t abuse my pump or cut corners.
So why is it not working right?!
You’d think a machine valued at $10K would actually work properly…
Our health and lives depend on this machine! It should work properly!
Of course I went online to look up these issues, I’m not the only one having them.
Of course I called the help line, twice. They tried but were no help. They told me to do the things I’m already doing to deal with the issue. Literally, they tell you how to stop the current symptoms but they don’t stop the problem all together. “Whenever this happens you’ll have to turn off Auto mode for a few hours, then go back in.”
“Whenever this problem happens?!” WTF, FIX THE GODDAMNED PROBLEM, MEDTRONIC!
“Turn off Auto Mode for a few hours…” The whole goddamned reason I got this machine was for Auto mode! I rely heavily on that very feature to keep me healthy!!!
It shouldn’t be happening at all and I shouldn’t have to keep dealing with the symptoms of a bigger problem!
At least I have my pump and CGM reports that are really good to gather information on my insulin usage and BG patterns. I’ve adjusted my basal presets to match as closely as I can to my average pattern when in auto mode. This helps a bit to keep my BGs more stable when I’m unable to be in auto mode…but it’s still not nearly as good as being in auto mode!
Please, if anyone can give me some advice I haven’t already tried to deal with these issues, please do so.
Otherwise I’m probably just going to toss this brick out.
