Lingo CGM Review: 3 faulty sensors in 4 months and a 20+ point discrepancy vs. lab work. Save your money?
To preface, I do not have gestational diabetes, but because of some borderline results, my OB-gyn said I likely have some insulin resistance so I wanted to keep track of my sugars.
I've been using lingo or the past 3-4 months with varying results, but after their customer service fail, I'm just upset.
I've had 3 faulty sensors. One died in 48 hours. The second caused bleeding, never started, and gave a "Biosensor ended early" error (Lingo app said they'd replace it; they haven't yet). Now, my current one won't pair with my phone.
Lingo is consistently lower than my fingersticks (sometimes only by 8 points, sometimes by 20+ points). During my 3 hour glucose tolerance test, Lingo peaked at 111 while the lab draws peaked at 133. I know CGMs have a lag/offset compared to blood, but a 22-point difference during a controlled test feels outside the margin of error for meaningful tracking.
Customer support: I messaged them about the bloody sensor and it took over 2 weeks for a reply. **They asked me to mail the sensor back—a sensor that was covered in blood which I had (obviously) thrown away 16 days prior.**
Honestly, I could call them but I'm very pregnant. Between 2x weekly OB appointments, insurance calls, and a stressful job, staying on hold with a tech company is at the bottom of my totem pole.
I think I’m moving to Stelo once I finish the Lingo sensors I have left. Let me know if anyone has moved over to Stelo from Lingo.
