Tandem really needs to fix their Mobi.
So far, I'm not aware of a Mobi insulin pump lasting a year. My first one was replaced after 6 months. My current one is 6 months old, though so far no problems.
They all seem to have a common failure mode: Piston drive starts failing and can no longer adequately deliver insulin, especially during a bolus.
I'm aware of several cases of this.
This is a $10,000 device.
