Ratings and reviews

Good, but not great. The point of using this for non-diabetics is to be able to track glucose response to diet and exercise changes. It's not optimized for this task, and since this is the only CGM I can buy without a script, clearly Abbott is aiming for this market. The glucose tracking is fine. However, it's the tracking of food and exercise is wanting. Can input general categories of food, but can't be precise. Just adding a free text "Notes" event would be very helpful.

The numbers are off sometimes, but keeping track of my sugar has been much easier with this product. It isn't very durable, though. After inserting it, it fell off a couple of times, which was frustrating. However, I contacted the company, and they replaced it without any hassle. One of the main reasons I continue using their products is their excellent customer service.

Valuable data wrapped in a mediocre app. Lingo has helped me reduce my A1C significantly. I'm unhappy, however, with the frequent connection difficulties, lack of info concerning how the Lingo count is calculated, frequent suggestions from the app to do ridiculous exercises, and weekly resetting of the Lingo count goal (which is not subject to preference). Finally, the app seems to encourage poor eating habits ( e.g., anorexia). That is concerning.
