Fair enough. Your first post directed at me sounded like you said it was here or will be here in the near future. Thats the problem by the time these things are available thewatch will probably be a dead item. Tech isnt there yet.
The other thing is to have your suggested ideas the watch would cost thousands.
All is good my friend
I would certainly be interested in a CGM that would cost $350, once. Meanwhile, in my world, blood testing strips are $0.80/ea (and I use 6-8/day), CGM sensor heads are $30/ea, and last a week, plus $800 for the transmitter and sensor electronics.
