amazing in the fact that someone (anyone) might wear that thing?? I agree then. umm, or maybe someone bedridden, nubian (no hair), and doesn't mind having a hybrid plugin receptacle looking thing attached to them might be interested.
The Echo sensor is tiny compared to the Medtronic needle that harpoons you to read your glucose. IMO Echo will steal all the Medtronic business because all diabetics will switch to the no needle Echo device instead of the old needles.
