Medtronic has a monopoly of sorts in the US. Last year they made a 'deal' with Medicare which is our system of healthcare for those people 65 and over. This deal demands that anyone whose pump warranty expires in 2016 and in the future, will be put on the various models of Medtronic pump. Never mind if the pump you are currently using is the one that works best for you or that you prefer it. Medtronic's cgm sensor leaves a lot to be desired and many are not happy about this new 'law'. Alan is right, there are people who don't give Medtronic a good review for good reasons. Their customer service absolutely is the worst at present.
