Just because something doesn't have the recurring razor blade model of revnue (as glucose meters currently do), doesn't mean a company won't make money off of them. Now they give you the meter, but I get charged about $0.25/test strip, so about $180 of revenue/year. I would easily part with $1000 for a watch or anklet like accessory that would measure my glucose without it being possible for me to forget about it. And I'm not even the best target market for it, because my sugar has never gone low. I had a coworker with a child with type I diabetes and they had to test her sugar somewhere around 10x a day. I'm sure a lot of parents would part with even more money than I would to avoid having to prick their child 10x a day. Edited to add: Actually, there are likely to be sophisticated electronics anyway, enough to have a timer. The only reason I can think of not to have a subscription based model (i.e. it will work for 1 year for $250) is that it might turn off more potential customers and overall revenue could be reduced.
