Because the Enlite sensor system is not yet available in the USA, many people making pump and CGM decisions are having to do so missing some crucial information. This is a good blog post by a young Type 1 from the UK comparing her experience with the two systems. It’s definitely worth a read if you are trying to decide between an Animas and Medtronic pump.
I have used the MM CGMS (not the elite), but switched to Dexcom. From what I've read/heard about Elite, I'll probably stick with my Dexcom due to accuracy and convenience.
I think the other key decision point is whether the low-glucose suspend feature is important. If that were a priority for me, I might upgrade to Veo with Elite when the new MM comes out in US, but at this point think not.
