  • Potential Drawbacks: CONS

      • Need to carry reader if app is not compatible with your phone
      • Must scan sensor and wait a moment to get data
      • Tends to ‘exaggerate’ lows & alerts for lows when not low
      • Calibration not available to improve accuracy
      • Can only add/edit notes within 15 minutes of real-time on Reader
      • It takes 3 hours to fully charge a low battery Reader
      • >500 mg daily of ascorbic acid (Vitamin C) may falsely raise Sensor glucose readings
      • Transmitter adhesive may not last 14 days
      • Need to use enough “force” to push the inserter device to deploy the sensor from the inserter into the body.
      • Aside from a momentary display after scanning to get a glucose result, the phone app only displays in 24 hour graph format which visually causes a more variable-appearing glucose graph than if it were displayed in a 3, 6, or 12 hour view. 
      • Still comes with a fine print warning of:  https://provider.myfreestyle.com/freestyle-libre-2-accuracy.html IMPORTANT: The device may inaccurately indicate hypoglycemia. The results of the clinical study conducted for this device showed that 40% of the time when the device indicated that user sensor glucose values were at or below 60 mg/dL, user glucose values were actually in the range of 81-160 mg/dL. Therefore, interpretation of the FreeStyle Libre Pro Flash Glucose Monitoring System readings should only be based on the trends and patterns analyzed through time using the reports available per the intended use.
      • A warning related to charging the Reader states: Surface temperature of Reader and power adapter could be as high as 120?F while charging. Do not hold the Reader or power adapter for more than 5 minutes while charging.
