I really wish that
Jay Radcliffe hadn't publicized the well-known security issues with my pump. I'm fairly convinced that that led to the lock-down on insulin pumps.
I've been looping for several years now, and the results are amazing. It's way more effective than any other therapy I've used (way better control, better A1C), but more importantly I now have a hardware solution that offloads about 100 decisions per day from my life. That part is truly life changing.
Unfortunately, my current device is held together with duct tape, and it's unlikely that any new hackable devices will be brought to market. I expect it will be 10+ years before the commercially supported devices provide the same control I've enjoyed from a home-built solution, since the manufacturers are understandably conservative/risk-averse.
