User Reviews
Best value in CGM
Switched from Dexcom to save money and I'm impressed. The Libre 3 accuracy is excellent and 14-day wear means fewer sensor changes. App works great with my Android phone.
Great for the price
The Libre 2 has been reliable for two years now. Sometimes the sensor fails early but Abbott replaces them quickly. The scan-to-read option is nice when I don't want constant alerts.
Finally affordable CGM
As a Type 2 diabetic, cost was my biggest concern. The Libre 2 is affordable even without great insurance. It's helped me understand how food affects my glucose better than any other tool.

Over-the-Counter (OTC) CGM Options
In 2024, the FDA cleared the first OTC CGMs, led by Dexcom's Stelo and Abbott's Lingo and Libre Rio, democratizing access to metabolic data.
Accuracy and Interstitial Lag Time
Continuous Glucose Monitors (CGMs) measure glucose in the interstitial fluid (ISF) rather than the blood, creating an inherent lag time of 5–20 minutes.
Insurance Coverage and Medicare Criteria
CGM insurance coverage has expanded significantly following the CMS 2023 update, with Medicare, commercial insurance, and Medicaid all providing various coverage options.
Sensor Insertion and Site Rotation
Proper sensor insertion technique and regular site rotation are essential for accurate CGM readings and skin health.
Interpreting Trend Arrows
Trend arrows on CGMs visualize the Rate of Change (ROC) of glucose, allowing users to predict future levels and adjust treatment proactively.
Troubleshooting Common Sensor Errors
Understanding the difference between technical failures and physiological artifacts helps users troubleshoot CGM errors effectively.
