I liked it, loved the general picture it gave me of my blood glucose levels, however wasn't very accurate compared to my meter when I was high or low, was out by 3 mmol/l, I called them to advise and they suggested the sensor may be faulty so got a replacement, however when I removed the sensor there was blood under it and skin quite red, also sticky bit wasn't very sticky and had started coming off too. Second sensor lasted 3 days before I hit a door frame and knocked it off..
I think this is a great idea for kids as parents can scan them while they sleep, as long as the sensor is pretty accurate, but you still need to test with a normal meter before driving.
