I've been using the Omnipod for nine years or so and moved onto the Dash a year ago as am hoping it’ll be a more natural transition when Omnipod 5 comes out which might be next year so I can start looping so that’s one benefit for you. The PDM is basically a cheap phone that is smaller and easier to program than the original PDM but as you know, it doesn’t have the blood testing incorporated as the original did. It doesn’t matter for me as I use the Libre with Xdrip and a Contour 1 for blood testing to calibrate and double check readings on occasions. The PDM is a bit cheap looking and isn’t perfect but it’s ok, it does need charging every few days though. Hope this helps.
