Medtronic pump is awesome. There are challenges to whatever we do in life; including changing anything we do. Learning a new pump is the same.
I've just become a pump user in the last 2 months along with the con't. sensor as I no longer am able to 'feel' when my sugar is low. Becoming confused, combattive and even having seizures due to the low sugar - here in the United States, we finally fought & got Medicare to cover the sensor.
My wife could no longer tolerate the highs, the lows = the unknown everyday. The pump has the ability to give bonus/carb intake per choice settings of all at once to even over couple hours & the bonus wizard will not let you give more than carbs' s amt based. Yes, you can over-ride the bonus wizard if so desired.
The company has 24/7 help line and they have talked us through mega problems; even sending replacement sensor products when being unable to do it correctly! (Re: unable to 'load' the device correctly into the 'insertor' & wasting 3 sensors before getting it correct).
The pump - insulin has it's own syringe (2 sizes) --depends on how much insulin used in 3 day period(150U or the 300u which I have). Gives you 4+hr warning when 'low' so you have plenty of time to get to reset up. Also, able to fill with either the flex pen or from a vial.
What a Godsend! ( my wife- ICU nurse/heart patients and using Medtronic pacemakers and other products with her critically ill patients for 20+years-- STRONGLY suggest the Medtronic device!!).
Oh, yes-- I have mega problems with absorption rates too due to being a DB 40+ years so I definitely understand your concern to "switching" to something new. Not only peripheral neuropathy with limb and toes amputations; I feel now the neuropathy has progressed even more upward to my stomach & its ability to digest at a normal person.
