Blood sugar fluctuates with different meals, not sure I constantly need to know that my blood sugar has risen after every meal. This device seems suitable for people for people suffering a lot of hypos or a loss of hypo awareness. It may however be an advantage to monitor how different foods can affect blood sugar fluctuations, by this I mean high fat versus low fat, proteins and different types of carbs. It will obviously be somewhat beneficial. As for not having to prick my finger, this never bothered me as I have to inject insulin any way. I'd prefer if someone would come up with a feasible  non invasive method of insulin administration, or even a cure. But why invest money in discovering a cure, when there is more money to be made treating it.
