For those who haven't seen the movie:
"The daughter wears a new type of wrist monitor that charts glucose levels."
– Does this device exist or is it fiction?
– If it exists, find the Make and Model please.
– Bonus question: how much does it cost?
– Bonus question: how does it work?
(unanswered bonus question will not count against rating)
FWIW the injection device also shown in the movie is made by Lily.
