I am all hooked up to my Dexcom Seven... it is sooo rockin my world!! Right now I am 92. I can't stop looking at it. We went to the Apple store tonight to get our laptop tuned up and I just wanted to stand up and scream, "I got something cooler than an iphone!! Come see my Dexcom!" Justin was glad that I refrained. Maybe next time.
I've calibrated it a couple times and it seems to always be within about 20-30 unites of my Ultra meter. So far so good. =)
