Like you I'm in my 60s although I've been T1 for 40+yrs, good control but MDI
I started on a libre, very liberating, 6 months ago. 2 weeks ago I started on an omnipod, it's great.
Plus sides. Easy for a correction bolus, variable basal, infinitely adjustable, I'm still carrying out tweaks to the settings. The PDM is pretty good too.
I think after 2 weeks, I'm starting to get the hang of it, my carb to insulin varies on an hour to hour basis, so I still need a bit of gumption and human input.
