I have the integrated MM CGMS with my pump - while I like it, and believe it has helped me manage my sugars better than ever - I am frustrated at the inaccuracy of the sensors. Great for trending - but I almost fall over when the reading matches my meter. I understand that there is a 20 min lag for interstitial fluid - but I also get the sense - from reading some other postings - that the Dexcom is MUCH more accurate than the MM. Any members use both and able to relate their experience? Thanks.
