Like "So if you are right and the various pump makers are giving us the wrong info , is there gonna be a class action law suit ??? Medical necessity to change every 48 hours ..... Sorry but many doctors don't agree with you doctor John .... I don't think the makers of my pump would give me false info . You are doctor awesome share your opinion but practice medicine else where ..... Not on this site .... I'll go with Medtronics pump instructions before I go with yours ..... My doctor is also very involved with my pump therapy and got me doing the 3 day change ..... "
