Should you TRUST This $30 Non-Invasive Blood Glucose Watch? Putting it to the Test.

Today, we have an intriguing product to put to the test: a $30 Smartwatch that claims to accurately track glucose levels without the need for any blood samples. In this video, we'll compare this watch with its closest competitors to see if this innovative technology lives up to its promises.

Join me as I run a series of tests to compare the glucose readings of this affordable Smartwatch with a traditional Blood Glucose Monitor and the widely acclaimed Dexcom G6. We'll examine four scenarios: morning sugar, low sugar, high sugar, and steady-state sugar, using all three devices side by side. Get ready for some fascinating head-to-head action and multiple finger pricks to uncover the truth.

You know the other watch being in such close proximity, plus the fact that the Dexcom uses wireless technology, may have interfered with the performance of the other watch, though I doubt it. You shouldn't have worn both watches on the same wrist or even had the Dexcom on at all when testing the other watch.

WARNING - This watch was pulled off of Amazon for being a scam

I am 91 years of age and have an accu chek guide me meter. I am so tired of finger pokes 3 times a day. A smart watch would be a blessing.

I'm currently using CVS branded meter and strips (made by Accu-Chek). I was using the Free Libre CGM, but Medicare doesn't cover it unless you are taking insulin—I'm not—and it was just too expensive. Since the CGMs do not measure blood glucose, but rather the intrastitial fluid, it's always going to be somewhat different. There's a 15 minute (or so) lag, if nothing else. I'm guessing that the watch is actually measuring something on or near the surface of the skin, therefore even more remotely related to blood glucose and even slower to respond. AFAIK, the non-invasive sensors that are seeking FDA approval use spectrographic techniques that shine light THROUGH part of the body, such as an earlobe or the web of skin between fingers, and thus sensing what is inside the body. I hope those reach the market soon.

Seems like you should only have one watch on each wrist.

Thank you for explaining everything about a non-invasive glucose monitoring because I was interested before ❤️❤️

[mongofan]

Thanks for this comparison. We should keep in mind that Dexcom is reading interstitial glucose, not blood glucose, so it is always about 20 minutes behind in any trend up or down. I was actually surprised by how close Dexcom was to the blood glucose meter. As long as they are close enough that you would make the same decision regarding insulin or carbs, these slight differences don't matter. I would say that Dexcom and Accu-Check were close enough as to be considered essentially the same.

As you said, though, the watch was so far off that it shouldn't be trusted. One would definitely have made different treatment decisions, some of them very different, based on the watch.

Thank you for this. I am not full blown diabetic, but in the so-called pre diabetes range, and for the last year or so have been monitoring my blood sugar - and touch wood, with life style changes, I seem so far to be able to avoid medication. But as to your result that surprised you, you should have taken that one, using the same device again. Every now and again, I will get a result that would indicate I'm way off where I should be. But so far, if I immediately question whether it's something to do with the test strip, and repeat the test immediately, I find that that is the reason. For example. I once got a reading on 7.9 mmol/l, but when I tested again it was only something like 6.5 mmol/l (still a little high, but!). So there must be some test strips that have a problem. If, on the other hand, you take two such readings, and you confirm the high reading, then you know that you have a problem.

My highly PERSONAL experience with the E600 smartwatch for 3 weeks:
1. You must do at least 3 measurements to get a somewhat reliable result. The average is close to the value of the blood test.
2. Yes, as much as I can see, the graph looks the same every day, independently of what I do, when and what I eat. So the watch is just 'guessing' or has some kind of built in bias according to the time of the day. It DOES some measuring, but it's accuracy is very questionable.

Nice Comparison, Very usefull to make final opinion without confused.

[winnguyen]

Thanks bro! I’m not diabetic but I’m pretty old and they are scaring me with all the info about glucose spikes and brain damage.

[justsittingherethinking]

Thanks for this information, it was really helpful. We bought a smart watch like this after being told that my husband was pre-diabetic and were wondering about the accuracy. Interesting test.

[larryse]

I use nothing at all, except my medical blood test for my doctor, I had my a1c shoot up to 9.2 in December and I declined medication and immediately changed my diet to Keto with an 18/6 fasting routine and in 5 months lowered my a1c to 5.9 and still dropping, my blood glucose is now 95 down from 175, I have lost 25 pounds down from 191 and I feel better.
Thanks for the great review with other forms of reference, others who review these just guess if they are working, Good Job and thanks.

[danmccann]

Thanks for the informative review. I'm thinking the cost is part of the inaccuracy. Something by a company with more invested in the tech may be more accurate as well. I'm using the Dexcom G7 and quite happy with it. The best part is that I can see my readings at a moment's notice. That really helps a lot in managing my condition.

[mohammedfarooq]

Great job explaining new blood glucose watch I like it love to have one thanks

[liquidmoonlightcom]

Just a note about testing. I too have an Accu-Check meter and it can give me widely different numbers when I do checks. In fact in 5 tries it may not give me the same reading twice. Sometimes the results vary greatly when using a different finger to test from. I have checked with my doctors and registered the variance in results but they don't seem concerned. My point is that unless we see it give you the same result on multiple tests, we have no way to verify it isn't off though I agree, it's probably more trusted by doctors. I would have been interested in seeing how much variance there was in the watch with multiple readings. I managed several QA departments and on something like this we would do anywhere from a minimum of 3 tests to as many as 10 or more to determine accuracy of readings.

When I checked on how the watches worked, it seemed to indicate they worked off perspiration. If so, it may be useful to make sure the watch is in good contact with a specific portion of the skin during it's testing time. And to make sure it is in the same area of the wrist each time. In the video it didn't show how well it was in contact with your wrist and you were wearing the Dexcom along side it. That probably makes no difference but it may. In testing I wouldn't put the two next to each other as there is a small possibility one may interfere with the other.

That said, I have not seen any medical evaluation on the accuracy of the watches and would want to see an independent labs evaluation of the non intrusive way of measuring blood sugar. Obviously if it is getting it from perspiration then humidity and sweat would make a difference in the readings.

I hope you will teste newer watches as they become available and perhaps see if different models are more accurate than the $30 eBay / Amazon watch. Do they get better over time as the technology become more common.

Thanks for posting your review.

Good content.. Best review video on non invasive glucose monitoring.. looking forward for more informative content..
I'm type 1 diabetic since 18 years
I'm using freestyle libre 2

[biglou]

I’ve not if not unusual to get different readings
I have 3 different glucose meters and test at the same thing always different results 😮

[mikefa]

BEFORE YOU GIVE THE WATCH AWAY - please re-do the test again because i believe the watch did not give accurate reading due to operator's errors - in order to get a more accurate reading on the glucose watch, you need to let the watch rest on your wrist without movement, or preferably, you gently hold down the watch on your wrist until the watch has the sufficient time to give the reading. Those health watches also have blood pressure readings and body temperature readings as well as oxygen saturation readings - perhaps you can consider testing whether those features are accurate on the watch?

[beckymastache]

Thank you for sharing the results of your experiment. Happy with my Dexcom G6 (besides the initial 12-24 hours after a sensor change). And no, I don't want the watch. You might be stuck with it. 😅
