The libre freestyle 14-day is usually within 15 mg&amp;#x2F;dl when the reading is between 80 and 100, but above that range, it is usually off by 20 to 30 percent of the correct value (not 20-30 mg&amp;#x2F;dl) and mine has never read much higher than the finger-stick test, only lower. The lower numbers make me inclined to believe it,  but they are simply not true, the meter gives only about one significant digit of accuracy throughout its range, and it is pretty far off or refuses to produce a reading when my blood sugar goes below 60 mg&amp;#x2F;dl.
Still, being able to see at a glance whether one is 100 or 200 is quite useful. Medicare pays about $500&amp;#x2F;month for the attachable sensors,  which are extremely convenient and non-problematic so far.&lt;p&gt;There is a far better wearable system ready to go but not in production, a combined sensor and automated insulin dispenser, that has passed human trials, but no one wants to go into production with it because of liability issues.  Given that people are riding in self-driving cars and landing in aircraft on autopilot,  each of which are also potentially fatal and involve a larger set of variables, I wonder if and how long it will take to progress in this regard.</text></comment>
