That is one sign that the technology/implementation is not as good as we dream it should be. Another sign is that in the one demonstration they did do they had a non-diabetic person wear it. Guess what, the numbers where good. If this thing really worked they would have youtube videos of T1 people wearing it and eating candy. They would be showing it off to endo's and at diabetes related conferences and allowing people to try it and blog about it. If not in the USA due to legal restrictions at least somewhere. So far, after over a year of having what they called a working prototype there is still not a stitch of independent evidence that it even works? Why?
