Non-invasive blood glucose monitor ads are everywhere. Ring Minds Glucose Monitor, Zakdavi, Clinclii, e.t.c They promise no finger pricks, instant results, and accurate blood sugar readings with just a finger clip.
As someone who’s constantly researching health gadgets (and tired of getting pricked), I decided to test them.
They looked high-tech. The promises were bold. But what I received — and what I experienced — told a completely different story.
Here’s my honest review of these so-called non-invasive blood sugar monitoring devices.
About Products
RingMinds, Zakdavi and Clinclii are both marketed as non-invasive blood glucose monitors or non-invasive blood sugar meters that work by simply clipping the device onto your finger. No needles, no sensors, no pain, just wave and go.
According to their ads, these devices use advanced infrared or laser technology to “accurately read your glucose levels through the skin.” Some of the websites even claimed it’s produced by American Diabetes Research and Support Agency, FDA clearance and displayed graphs of blood sugar fluctuations, trying hard to look clinical and legit.
My experience using Non-invasive Blood Glucose Monitoring devices
After being bombarded with ads, I ordered three different non-invasive blood glucose meters and waited. They arrived after 15 days, not from the U.S. like the websites implied, but straight from China, in unbranded boxes with barely-legible English instructions.
Both looked like cheap pulse oximeters, the kind used to measure oxygen levels and heart rate and that’s exactly what they were.
When I put them to the test, here’s what happened:
- The screen showed my pulse rate and oxygen saturation, not blood glucose.
- The so-called “glucose reading” was stuck in the same range no matter what I ate or drank.
- I tested them back-to-back after a high-carb snack and then again after fasting — no change.
- I even had someone else try it, and guess what? Same glucose number, different person.
It was clear: they weren’t detecting blood sugar at all. Just pulse and oxygen. That’s it.
These were pulse oximeters pretending to be blood glucose monitors. And they cost me way more than a basic oximeter should.
Is This a Scam?
Yes, 100%.
They are not real blood sugar monitors. They do not measure glucose levels, despite what their marketing claims. The truth is: they’re rebranded pulse oximeters, likely bought in bulk and slapped with new names to make them look like high-tech medical devices.
The websites make them look like they’re from U.S. companies, but they’re actually drop-shipped from China. There’s no FDA approval, no proper glucose sensor, and certainly no magic technology.
Worse, these same devices are being sold under dozens of different names; Biancat, and including big-sounding ones like Omron, which has nothing to do with these scam versions.
Please know: there is currently NO truly non-invasive blood glucose monitor available for home use that can replace finger pricking or interstitial fluid sensors. If you see something claiming otherwise, be extremely skeptical.
Are There Any Real Non-Invasive Blood Glucose Monitors?
This is where it gets tricky. There are some promising technologies in development, but they are not yet widely available or FDA-approved for home use.
Some names to keep an eye on:
- Know Labs – Uses radiofrequency to detect glucose through the skin. Still in testing.
- SugarBEAT by Nemaura – A patch that’s non-invasive-ish (pulls glucose from the skin), approved in Europe but not FDA-cleared yet.
- GlucoTrack – Clips to your earlobe. Approved in some countries, but not the U.S. Accuracy is still being questioned.
So yes, the future looks exciting. But for now? Don’t fall for the hype.
Best Alternatives for Blood Glucose Monitoring (That Actually Work)
Better Blood Glucose Meters You Can Actually Trust

The Bottom Line
These non-invasive blood glucose monitors don’t measure blood sugar, they’re not FDA-approved, and they’re not new technology — just misleading, overpriced gadgets.
If you see a non-invasive blood glucose monitor being advertised with no finger pricking, instant results, and a huge discount? Think twice. It’s probably the same scam device recycled under a different name.
I learned my lesson the hard way, but you don’t have to.
FAQ
Do non-invasive blood sugar meters actually exist?
Not for accurate, FDA-approved home use. Some are in development, but nothing is available right now that can fully replace pricking or CGM systems.
Are Zakdavi and Clinclii real blood glucose monitors?
No. They are pulse oximeters disguised as blood sugar meters. They cannot read glucose levels.
Is there a way to monitor blood sugar without finger pricks?
Yes — through CGMs like Freestyle Libre or Dexcom, which use tiny sensors just under the skin. Not completely non-invasive, but far more convenient than traditional meters.
What are the safest alternatives?
Stick with FDA-approved tools like Libre 3, Dexcom G7, or smart meters like One Drop and Dario. Avoid anything that sounds too good to be true.
Thank you so much for this review. I was so tempted!! Now I know…. NOT!!!!
Thank you so much for this review.I’m84, Type 1 Diabetic for 27 years, When I first saw ads about these things I almost jumped on it….sure glad I did some more checking! Thanks again!
If you bought one of these, please post a review to TrustPilot.com
If the vendor tells you to return it to China, it will cost more than it’s worth. They’ll then offer you a partial refund. This is common for all kinds of scams including “handcrafted” jewelry, health gadgets, etc. Review it and dispute it with your credit card. Please.
The item in the ad looks exactly like my pulse oximeter, which measures pO2 (blood oxygen, usually around 95-100%) and heart rate. That 90-something reading ISN’T your blood glucose. You can get a better one at CVS or Walgreens and they’ll take it back for a refund.
IT MAY BE A REVIEW BY A TEST STRIP COMPANY LIKE ACCU CHEK OR ABBOTT…………..
True, I fell for the same scam.
Everybody advertised non invasive blood glucose monitor.
But they ship a useless oximeter.
I got 2 iunder this scam.
What a scam
I was considering Zakdavi for a loved one who is struggling with the cost of glucose testing supplies. I cannot thank you enough for your integrity, clarity, and honesty. Such rare qualities these days, and so appreciated. Thank you also for recommending alternatives and specifying their limitations.
Sorry to hear this is a scam. I’m more sorry I fell for it and bought one–well, I paid for one! I haven’t seen it yet. I checked their spooky tracking site, and it says my glucose meter was indeed shipped from China. Then yesterday it says it has “arrived to its destination at JFK.” That would be in New York, I’m guessing, But I live in Utah!! Perhaps it’s being secretly shipped for delivery by some unknown alien. . .if ICE doesn’t get them first.
I tried to order one of those. The bank closed my account because there was fraud activity. One bank called me and asked me about the product. I told them that I was unable to call them up or contact them in anyway. So they must be a scam.
Zakdavi advertised a glucose meter and I made a purchase. They shipped an oxygen meter instead. I responded that they shipped the wrong product and I wanted them to ship the product I ordered. Their response was for me to send them pictures of the wrong item and shipping package, which I did. They responded with an offer to give me a 50% refund upon which I insisted they ship me the item I ordered. Without consulting me they processed a full refund.
I later made a second attempt to purchase a glucose monitor. I ordered a glucose meter from Coopinks company and they also shipped me an oxygen meter.
It makes me wonder if this an industry practice to advertise a glucose meter but ship an oxygen meter.
I also notice that many ads provide a description of a glucose monitor but show a picture of an oxygen meter.
I was tempted to buy some thing like this. Thank you very much for your info.
This review is dead on in all counts.
ordered and glucometer for $19 and change ($38 with tax and shipping). Got an oximeter. Difficult, but I finally found the supplier in China who made it damn ner impossible to return and get the right item with no assureance there even such a thing. Plus, the cost would been rediculous. This whole business is a scam and rip-off.
I was a bit leery about ordering one and haven’t. Thanks for your review and won’t. For anyone that did, please contact your bank to dispute the charge since it is clearly a scam. My bank gives me 90 days to dispute charges, and I have done so a few times in the past with positive results. Big chance you can get your money back from your bank. It doesn’t hurt to at least try. Good Luck.
Thank you for your valued honest input on these non-invasive glucose monitors. I got tired of pricking my fingers years ago. So, I stopped pricking myself. I want to monitor my blood sugar because I am Type II diabetic. I have been watching what I eat and I have cut way back on how much I eat. I try to eat healthy and yes, I do have a few sweets here and there. I watch how much I have.
As for the FDA, they are a joke. I do not trust them. How is it that they have “approved” harmful ingredients in a lot of our foods here in the U.S. and those same ingredients are banned outside the U.S.? Funny how the FDA turns their heads to these harmful ingredients that is causing different illnesses in millions of people here in America. The FDA needs to be held accountable for poisoning Americans with harmful ingredients. Plus, there is a lot of “hidden” ingredients given a different or generic name to “hide” those harmful ingredients from the consumer. Again, the FDA is a joke. Everyone “needs” to read the labels of all their food items they consider buying and check the list out to find out what those strange names in the ingredient list are and if they are bad for human consumption before buying those products.
There are also products that contain bugs in them and most people have no clue they are eating bugs in some of the products they consume. If I did not know any better, I would say the FDA has bought off food manufacturers to add these harmful ingredients into different foods to boost illnesses to feed the medical community. The medical community needs repeat patients to fill their greedy pockets and the drug companies as well. There are some good doctors in the world and sad to say there are a lot that are bought off my the different drug companies.
I am sure there are many other apps we can use. These are the ones I use and they do help me.
I hope everyone who reads this comment will consider what I am sharing and take note that all of us must be diligent in taking control of our own health as well as our loved ones a friends.
We need to get back to the basics of eating foods that do not have preservative additives.
I hope and pray this information will be helpful to each reader.
To your good health.
I was exvited about the ‘technologhy’ and idea, tempted to get one, but decided to read reviews first….you said me the money and frustration.
Yes. Thank you all for the great reviews. There are no non invasive blood sugar monitors at this time. I wish there was a way to get the general public to know this. An absolute ripoff by a bunch of crooks.
