FreeStyle Libre 3 Sensor (2-Pack)
The FreeStyle Libre 3 System is the only CGM able to maintain accuracy over 14 days without needing fingerstick calibration or sensor coding and also gives your first reading just one hour after the sensor has been applied.
The sensor for the FreeStyle Libre System is small, discreet and water resistant.

Little bit inaccurate

HARISH · August 16, 2026

Worse than not wearing a CGM

I've been wearing this a few days and it is unpredictable and wildly inaccurate. I have zero confidence in it, it's worse than not wearing a CGM at all. It's usually a minimum of 30-40mg off (always low), will read 55 when a fingerstick says 95. Dangerous low alarm going off when I'm over 100 on fingerstick. I bought these Libres because they're a bit cheaper than Dexcom, but this was like throwing my money away. I don't have a prescription so I'm not sure that Abbott will even replace it. I've worn several Dexcom 7s and never had a dud like this. Wish I hadn't bought a 2-pack. It cannot be calibrated like Dexcom, and also does not sync with my Apple watch.
