By the way I want to acknowledge a huge debt to everyone who stuck it out with pumps back in the day when they were only 85% reliable, then 90% reliable, then 95% reliable, etc. Without the efforts of those people pumps would not have improved to the reliability they have today. Still not perfect but vastly improved.
I think the problem I faced as much as anything is maybe the improvement trend going into reverse, on infusion sets, as the technology "matures" and they start to think they can cut costs and cut quality control on the manufacturing of these expendable but vital components.
