Sorry to hear that Karen, first pump 4 years ago was a insight , had some problems with the teflon cannulas ie useless on the right side of my body,  poor absorption, when I worked well i was using 20% less insulin  compared to mdi, since changing to the ypsopump and the steel cannulas it's  been brilliant,  25% less insulin than mdi and a in range of 95%, it's not tubeless  and you can't bolus from the app . I turned down  the omnipod due to the cannulas and  maybe that's the problem for you,  hope  they can sought you out x
