My spouse is type 1 diabetic and I got her set up on Loop a few years ago.

It’s out of this world how much work she had to go through beforehand. Several times per day she had to babysit her shitty pancreas or she will literally die. Read a number from one device, apply some rough mental math, and insert a different number into a different device. I’m honestly confused it wasn’t automated sooner.

I’ve had numbers wear off (never went by them anyway) and rubber gaskets wear down, but a $5 gasket replacement every several years still counts as BIFL for me. The plastic argument makes sense, although I haven’t experienced it. They just changed their materials for the clear version, I wonder if that one is better.
