I think it’s completely normal to feel apprehensive

It would almost be more surprising if you weren’t a bit anxious about it.
My first experience of sensor-augmented pump was the Medtronic MM640G which had predictive low suspend. It worked really well for me. I absolutely loved turning off the alarms that told me when the pump was *doing something*, and then finding out with the on-screen prompts some hours later that the basal suspend had dodged a falling glucose and got me back mid range while I was busy doing other things. It was the first time a piece of diabetes kit was
actively helping me by itself, rather than me having to make all the decisions. The MM640G caught lots of little dips below 4.0 for me, but of course it couldn’t catch them all.
My first experience of HCL was with the Tandem tSlim, which gave me the best numbers I’d ever had up to that point, especially overnight. My nights became beautifully boring. Whatever chaos had happened in the evening I’d wake to a steady 5.5-6.5ish every day, with virtually no alerts or alarms in the whole 4 years of nights. In the daytime however, the algorithm acted a little too gently, and a little to late for my diabetes (they all have their own quirks), so I had to rely on alarms more, which was quite fatiguing in the end.
I’m now back on Medtronic with the MM780G. This algorithm seems to suit my body better, and I can leave it to do its thing most of the time. I miss some of the flexibility of the tSlim, and have had to develop some workarounds, but overall I am preferring it. I spend less time thinking about my diabetes day to day, and my results with it are great 90% TIR, and only 1% of time below 4.0 over the last 14 days (which included several celebrations, meals out, beers, and takeaway).
