My second pump was the Ypsomed I really liked the size , look and simple ease of instructions and user friendly , I then had a choice of Ypsomed , T slim and Medtronic ( which I had used before and hated and was lucky enough to switch to Ypsomed after using Medtronic , can’t remember what model Medtronic was . I am now on Medtronic 780 with Simplera sensors , I loved the look of T slim but it was a wait to get , Ypsomed software not compatible with iPhone so my diabetic team steered me towards Medtronic 780 and I love it . Only gripe is a bit big to fit in pocket also I use 7 day infusion sets work well for me .
