Lingo Continuous Glucose Monitor (CGM) & App. Made by Abbott. Know The Impact of What You eat. 1 Lingo biosensor Lasts up to 14 Days*. Designed for iPhone 11 Device or Later. US Only.

The lingo is great little piece of technology. It has a small profile and it works well. Here I address the major points:1. Accuracy: I'm on my second lingo, and I compare its reading with TWO separate True Metrix glucose meters. Every time I have checked, the lingo reading is between the two reading from the True Metrix meters. So the lingo is never far off from what is the true value. The sensor does read low if you compress it, like when you sleep on it. But that is a minor issue.2. Ease of application. The applicator is spring loaded and the unit goes on without a hitch. Don't be worried about what looks like a needle -- I feel nothing from the puncture when it inserts. I inspected the unit after removing it, and the probe looks like a flexible short piece of hair, so very thin and unobtrusive.3. Sticking power: I bumped my first unit several times and it stayed on just fine. I prepared the area by shaving my hairy arm and cleaning it with isopropal alcohol. That seemed good enough. It finally came off prematurely after I got really sweaty and pulled of my shirt, which was sticking to my arm. I didn't feel it coming off an found that it had re-stuck to my skin a couple inches from where it had been. So I just washed my arm and applied a new lingo sensor. I purchased the little sticky pads that one can place over the sensor to protect it from accidental bumps, and that seems to work well, making it less likely to be pulled off.4. The app: It works well and provides a running plot of the glucose data in 5 minute intervals, taking a running average over the data that is taken every minute.5. Customer support: Support is great. They respond quickly and take care of the issue. My wife had a defective sensor and it was replaced right away.6. Data: You can contact customer support to request your data, which they provide by email in CSV format. Two suggestions here: (1) It would be nice to be able to download the data electronically without the need to request it by email. (2) I would like to have the minute by minute data so that I can analyze the statistics. They tell me that they are working on electronic access but I have not heard back about getting the minute-by-minute data.Overall, this is a great little device that helps you see which foods and activities affect your blood glucose. And, it's nice having long term data to compare it with your A1c. In my case, it appears that the A1c results are much higher than reality.

First off, the business model is brutal. No refunds on the sensors – tough luck if it doesn't suit you. You have to subscribe long-term! It's not like you can buy a pack of sensors and be done with it. No, it's like they lock you in.Secondly, what you get is extremely expensive, but the joke is you STILL have to do fingerstick calibrations with a regular meter! Like, seriously? I'm paying all this extra money specifically not to do finger pricks, but Lingo makes me do them anyway? What's the actual benefit then?All just to upgrade from “pricking the fingertip” to “pricking the arm + pricking the fingertip”?Continuous blood glucose monitoring is truly ridiculous.Blood glucose levels naturally fluctuate in healthy individuals! Eating an apple increases it by 2 mmol/L, and climbing stairs decreases it by 1 mmol/L… For someone like me with diabetes, the fluctuations are slightly more pronounced, but I don't need Lingo constantly reminding me. What use are these meaningless data other than to exacerbate my anxiety?Why not just prick the fingertip a few times a day—simple, inexpensive, and does not create panic!If CGM cannot replace BGM, why spend so much money and go to so much trouble? It feels like paying for a sports car but still having to push it everywhere. This is a complete and utter scam.And lastly, having this thing stuck in my arm sucks. It rubs against clothes, gets caught, and constantly irritates the skin. Half the time, I end up with this ugly, red, swollen bump underneath it that's itchy or sore. Plus, let's not kid ourselves – jabbing a filament under your skin and leaving it for days? That's just asking for trouble, like an infection waiting to happen. It's expensive, it doesn't deliver on its main promise, it irritates your skin, and they've got you by the wallet. Honestly, it feels like more hassle than it's worth a lot of the time.
