When I got my pump, I thought they said three years, I have been told the vibe is more up to date, and can correct low and high reading automatically. When I spoke to my consultant she said it came with a cgm, no mention of cost from myself. If I do have to wait the four years, I still want to stay with animas, they are a good company, and I like their pumps. I would like one without the tubing which the vibe has. I will discuss it with the hospital when I go next month, thanks for the replies.
