I’m a massive fan of Control-IQ. It’s life changing. The only time I have a low I have to treat is if I didn’t like dinner and didn’t eat anything remotely close to what I bolused for, when I was running a wicked fever (actually needed the glucagon for the first time in 20 years, it was a scary fever!), or intense exercise that wasn’t anticipated (chasing cows that got loose of the fence). And those are daytime lows… Nighttime lows are 100% completely eradicated (excluding something like that crazy fever), because of the “sleep” activity setting. The pump will flatline you somewhere between 110-120, unless you tweak your settings to target a lower value.
The pump doesn’t wake you up at night with Control-IQ.
That said, you’re completely in control of how it behaves, because it adjusts insulin according to the settings you enter. It’s not trying to figure you out like Medtronic’s system. So your success with it depends entirely on your ability to understand and correct/adjust settings…or at the very least having a capable medical team to help you do so. If you program a correction factor (ISF on Medtronic) that is too high, it will cripple the pump’s ability to adjust your basal. You’ll be stuck in whatever direction you’re heading, whether that be low or high. The pump generally behaves happiest with a lower correction factor than expected, but if you set one TOO low, Control-IQ will over-correct on both ends of the spectrum, resulting in both highs and lows before it changes direction.
You can expect to have to adjust your settings coming from Medtronic. Because of differences in delivery, absorption, and accuracy, your insulin needs will most likely be different. Because of this, you will probably dislike Control-IQ right out of the box. But opinions unanimously change once the settings are tweaked and people fall in love with Control-IQ.
I didn’t earn your bonus points, so I’m summarizing what I’ve seen in the Facebook groups… Which you’re welcome to join yourself. The “are you happy you switched?” question is asked several times a week. T:slim X2 was my first pump, and I loved it for 2.5 years before Control-IQ was evev introduced. Now that I have Control-IQ, I can’t imagine giving it up. I actually joined a 780G Facebook group, because my own warranty is expiring this summer and it’s time to start re-evaluating the options. The 780 looks like a vast improvement over the 670, but it doesn’t seem nearly as impressive as Control-IQ.
