Alright, it's been a few weeks.
Went to my endo today, and he totally supported my actions and thoughts.
He says the problem basically is that this company is american. jk
No seriously, it looks like this pump company prefers to sell somewhat crappy sensors over getting sued. or that is what my doctor said. what happens is, that each time the pump is slightly unsure about the data it receives from the transmitter, it prefers to say: no data received, and after a few times: sensor doesnt work, please replace.
that way the company protects itself from lawsuits against itself, because they cannot be responsible for wrong results of their sensor, because basically there aren't any. does this make sense?
so here i am, still slightly pissed off about this whole thing, and i will continue on MDI. I am not unhappy at all, and my endo gave his blessing, wrote me a prescription for Tresiba (another basal insulin, i had been using Levemir up until now, which i already had a prescription for). he thinks i will have better results with it. he gave me as well a dexcom receiver and transmitter from the hospital, which i can use until my exams are over in february. i will probably make my final decision then. i still have my pump, but it is in a corner in my room. if i decide to go with MDI and dexcom for the long run, i'll return my pump and stop my contract with medtronic.
it makes me really sad, i have been a happy customer of theirs for over 10 years (more than half of my life), but if they just cant keep their ■■■■ together then that is my only way (not only only way, i know i can change pump brands, but so far this is my only preferred way).
also, i can still return in a year or whatever time it takes them to fix their problems.
