@joe - From what I found the 7 day Medtronic infusion set has multiple insulin release/drop points in the cannula. It spreads the releases to different cells over that time period to not abuse the same cells over and over like other infusion sets that only have one insulin drop location at the end of the cannula. Hope the other infusion set companies can come up with a similar capability.

I really don’t experience any improvemnts. The name suggests IMHO that the reservoir can contain more insulin, which obviously is not the case. More important is that still after three days the infusion set starts leaking.

Hello @Isarin Jan welcome. I could get about 6 days with a 300 mL reservoir after that I would have to be able to change reservoirs without changing the set. When I leave a regular set in more than 3 days I tend to get irritated. When you say leaking… is it a physical leak or are you noticing higher blood sugar?
@Isarin Welcome Jan to the T1D Community forum!
Fro mem the size of the reservoir would not limit my use of “extended wear” infusion sets - a full 3 ml reservoir would last me 2 weeks. And infusion sets that leak? during two decades the handful that leaked fir me were all do to someone/something grabbing my tubing - and I’ve been known leave infusion sets in for 5 days without problem.
Note that there isn’t any “rule” that requires changing an infusion set and reservoir at the same time. A common practice for me, so I wouldn’t waste insulin, has been to replace an infusion set and keep in the reservoir untill empty; I’ve also done the reverse - though much less often.
Think through the steps before doing this, really quite easy.
