I appreciate your frustration with the Roche Insight pump. E-57 errors,slow response from handset and poor battery life i had this all the time from receiving this pump back in July 2015. But my final straw was I had to return back to MDI after four and half years pumping (Combo & Insight) due to the safety recall of the steel cannulas. I was offered the Animas Vibe last week but the bolus delivery speed was too high for me due to my lipohypertrophy and my poor absorption rate. I need a pump with a delivery speed of 0.15u/sec which actually the Insight pump does have and less, and did work very well for me without any problems. So my DSN is trying to obtain a loan Medtronic 640g, which I am told could take several weeks at the present moment. Hence no other option but to return to MDI which is highly frustrating to say the least. I think it very much depends on your hospital team and if you can put up a good case to have your pump changed. In my experience Roche's standard response will be to only offer you a replacement Combo pump and they will not refund the cost of the pump back to the local hospital trust. So unless the existing pump can be transferred to another person who wants a Roche Insight pump....then it's going to be difficult to swap I guess.
