How exciting! Please do let us know how you find it. No-one has answered my two posts so I am still trying to find someone who has swapped from Medtronic and has tried both to compare. My team say I can swap and have set things in motion (my Medtronic 640 went out of guarantee in May). I was going to wait for the 780, but I am beset by calibration requests at night and really spooked by the 'back order' of supplies for the Medtronic, and worried about what will happen after Brexit. I want a supplier who is in this country.
