The best money I’ve ever spent!
This has been so enlightening! I’m a thin, very active, and very healthy eating 60 year old with an A1c just barely in the pre diabetic range (5.7) per my last physical and lab results. I was shocked. So I bought this to see if I could find out when my sugars were high and after what foods. Well I was shocked again to find out how high my sugars went and how frequently I get big swings. I’m on my 4th day and have finally figured out through trial and error my diet and activity level and timing to give me a good Lingo score. I found that I need to eat less carbs (even though all were whole grain) and less fruit (I love fruit!) and only after some protein but mostly that I need to eat smaller meals and to stay active for about an hour after each meal to keep my sugar levels stable and from peaking so high. Yes it’s a little bit of a hassle but something I can do and so much better than medication or worse – having diabetic complications down the road. I would never have known without being able to have a constant monitoring system! It’s very easy to place the monitor and painless. And the app is easy to use. This will change my behavior and prevent so much pain and problems in my future. I cannot recommend this high enough if you’re pre diabetic or if you just want to have your eyes opened regarding what your sugars are on a real time basis. The best fifty bucks I’ve ever spent!It’s now 7 days later. The monitor stopped working on day 6. I called Amazon and they gave me a full refund without any problems. However, I still think the information was life changing for me. I would have liked more time to try different foods to see my body’s response, so I will try another one. I’m going to keep my rating at 5 stars because of how incredibly enlightening it was even though it only lasted the 6 days.

Installing the app
If this sensor is useful or not, I will never know… because I could not get it to work.To apply the sensor to the arm is easy and you will not feel a thing.To install the app is a total different issue. I have a Samsung Phone and I use this phoneexactly for the reason intended by Alexander Graham Bell and nothing else… like most seniors my age.I do not care one bit for all this nonsense and pretend functionality on a modern phone.Actually most phones are virtually unusable because the keyboard is too small for old fingers.But I did managed to “register” for a Google account. They of course ask me all sorts of questions which are none of their damn business… but I suffer with dignityso I go to the Google Play Store and search for “Lingo” and installed the app.The app started with asking me all sorts of questions… again, none of their business. I paid for the sensor soI should be able to use it, but no… they are more interested in my info.Then 10 or 20 pages later (i did not count) finally the page which read:Ready To Scan… I did hold the back of my phone directly onto the sensor which I had already put onto my arm.and …. nothing… then the message… Pairing Error… I tried numerous timesThen I called the support line and as expected a gentleman with a heavy indian accent ( you recognize the accent when they call you and try to con you out of your money, never pick up the phone when you do not recognize the number).Obviously the guy talks too fast, uses unnecessary words and you cannot understand a thing.This went on for good 1 hour and nothing. among other things, he asked me to delete the app, reinstall this and then search for a red dot… ??? what red dot??? I still do not know what he meant.Anyway I told him, that I cut my losses and tell everybody about my ordeal.Then he suddenly offered me to replace the sensor. Very well I am down $50 already, might as well… arrives in 2-3 days, meaning 4-5 days because of the weekend.Why is there no “app” for this sensor on a PC. After all A PC has a screen I can actually see and a keyboard which does not require baby fingers.And for Pete’s sake, do not ask me all these dumb questions, which are none of your business.If the replacements ensor works, I will try it… but then never again.Simply measure your morning fasting BG like before and that is that. Minute to minute updates are superfluousand expensive technology and a pain in the rear.12/21/25 1:14pmImportant update.I did not want to wait for the replacement and ordered another one yesterday from Amazon same day delivery. This one worked, but did not give me any reading for 1 hour and afterwards it was 20 points too low compare to the finger stick (73, 92).however this morning it was a lot better, In fact just now it reads 92 and the contour next fingerstick reads 95.I am more than happy with that.To be sure I get some benefit from this device… after all I learned that overnight my BG dropped to 55 for a brief moment… I seriously doubt that. All you can see trends, and I am lucky with this one, it is even accurate…. but I am an EE and I did work with large continuous datasets which were contaminated with large random errors and judging by the graph, it looks very much like a data set processed using a Markov Process. This is a mathematical process to get the best up to date measurement even when the whole data set is contaminated with random errors.But there is no free lunch in mathematics, nothing beats accurate measurements, no amount of math and statistics will make it better, even when it appears like that.In the moment I am happy… lets see, if the other reviews have a point.besides, why do you want to measure something you already know? Sugar and refined carbohydrates spike your blood glucose… its common knowledge… don’t eat junk food and you do not need a CGM,Everybody who wears a CGM or reads this post, has already done the most important thing, which is educating oneself about nutrition… everything else is superfluous.Important update 05/Jan/2026I am on my 2nd sensor. They last only 14 days for whatever reason, most importantly I guess, the glue will not stick much longer than that, probably the skin will secrete oils which dissolve the glue???The good news was, that removing the old sensor was easy and it left no mark on my skin other than a tiny hole where the sensor was inserted.Unfortunately, the second sensor is also about 20 points too low, relative to the test strip. Of course one could argue that the test strips read 20 points too high, which I seriously doubt. Consecutive testing with test strips (Contour Next EZ) show readings within 5 counts of each other using brand new test strips.Overnight I get readings of 55 with the CGM, which is utter nonsense, because I am a recovering type 2 diabetes patient… even a reading of 75 overnight is hard to believe.The only useful thing I have discovered is that overnight my BG drops significantly. Morning glucose measurements are virtually useless, because of the classic BG spike after waking up. As soon as you out of bed, the BG is already on the rise and it can go up 30 maybe even 40 points within minutes and you have no way of knowing on which part of the curve you are measuring.So again, I have a warm feeling that maybe I have conquered my insulin resistance, just add 20 points to whatever the CGM tells you and when this is under 80 during the night, you maybe ok… still avoid carbs for the rest of your life

Impressive device that’s improving my life
A friend of mine was visiting me when she started to check her “glucose reading” on her cellphone. I thought she meant a finger stick result, but she corrected me saying it was a continuous monitoring device. I was impressed by the thing. (I love gadgets!) My own labs had pointed to “borderline diabetic,” which was anxiety producing. Having been an RN in a large hospital, I had seen the results of full-on diabetes, from losing fingers to losing kidneys and developing transplant complications. Not going there!I checked the internet to see what they had to say. It seemed rational, well tested and produced by a reliable company. I decided to try it. It seemed a little expensive as a “One off” trial, but I decided to see for myself. I was—and continue to be—impressed.What struck me most favorably is that it’s a “training device” as well as a simple minute by minute monitor (which it is of course.) It provides the user with information about his/her eating habits and offers “challenges” that can help the user see what they can accomplish on their own. It also has small discussions regarding eating styles and recommendations about healthy activities. It also provides “challenges” that help you focus on things you might have thought unimportant, but which really aren’t, like fluid consumption.Probably the most important aspect of the device is the opportunity to log information about one’s activity, because it engages the user in the whole process. That confronts one with the reality of behavior and outcomes. (It’s also addicting. There’s nothing like making oneself the center stage character in one’s own drama!) There are note sites for “food and drink,” “exercise,” and “other.” These are placed along a timeline under the graph, so one can see what was going on when the graph went up or down. By doing some of the “challenges” one learns how much one’s own decisions make an actual difference.Food and drink, and exercise are obvious. I use the “other” for charting things like my blood pressure, pulse, sleep, mood, willingness to be active, fogginess (I’m almost 80 and am forgetful at times), and other things relative to my overall health. In following these through time, I came to finally realize what modified these aspects of my life by diet choices alone! As a former RN I “knew” that but didn’t practice it; I just advised it. (That was “for other people,” of course; I was Wonder Woman—the suit has long since been sent to Good Will!)The normal parameters on the graph showed me that my glucose was peaking above 140 even to greater than 200 at times, then crashing shortly thereafter to below 70. Needless to say, I was foggy, tired even after sleeping to the point that my cats were trying to determine if I’d died and there’d be no breakfast today. I’m more energetic, have started doing crafts I’d not done in ages, read more, my thinking is clearer, I no longer wonder why I decided to cross the room in the few seconds it took to get there, etc. I ask you, what’s to lose for a few dollars?
