Has anybody upgraded their medtronic 522 to the new revel 723? My daughter is about due for a new pump and at 13 I'm thinking that we should get the bigger resevoir. The most insulin she uses daily is 30 units and in Feb it will be 5 years since dx. She is also incredibly active. She is probably just now starting puberty so I think the bigger resevoir would be important but she and I are wondering if the increased size and slightly different shape of the 723 will bother her. Anybody?
