ypsomed pump .
very good pump when it works as for me and were i ive blue tooth problems but good luck .
and if you have finger problems get some kind person .to fill up 6 vials for you that is roughly what i get out of i vial of insulin get the black storage box about 2 inchs wide can store 12 vials that fot in pump takes about 10 units on refill
also let cartriges sit in room temp for about 30 mis this stops air bubbles from forming very veryslow to pull plunger down to refill onwards and upwards ELENAP
VIC STILL LEARNING AFTER 68 YEARS ON INSULIN
