All over the world, companies are working towards non-invasive blood testing, Glucowise, Glucotrack & Grove Instruments to name three... a few years ago the Libre was a twinkle in someone's eye.
There's a huge market out there for reliable, easy-to-use, non-invasive blood testing, so hopefully it shouldn't be too long.
I agree with Tim2000 that most diabetics, type one or two, dependent on the advice given to them strive for good control.
As an aside, an interview by Stephen Dixon on Sky News interesting from the point of view that Stephen is a type one diabetic & that when he mentioned the Libre to the professor, said prof didn't seem to know what he was on about.
As someone who has given up the Libre due to skin irritation problems, I can't wait for the net generation of testers....
Edit: Just to add the other side of the coin, Grove have filed for bankruptcy in the States...
