Selling a Medtronic 722 pump that is compatible with Loop and OpenAPS. It is firmware version 2.4a.
No major body cracks, the buttons all work, the alarms sound, and the motor runs smooth. There is some wear around the reservoir lock, as is to be expected with a pump of this age, and the battery cap was replaced (it is blue). I have used this pump with both Loop & OpenAPS without issue.
Shipping (US only, sorry!) is included, and you will be provided a tracking number.
