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
