Sam was in a Dexcom Gen 4 trial--in our opinion a MUCH better sensor. The gen 4 system is an updated sensor and software including a new pediatric algorithm and from what I understand the new system has a new receiver with a smaller, more traditional shape and color screen. Heather - take what Animas says about the Vibe's release with a grain of salt. We've been hearing "next year" from our rep for 2 years now. Now when we ask him, he rolls his eyes and says who knows. The FDA is holding up device approvals big time, so it's impossible to predict new device availability. What I'm saying is ... don't bank on it.
