iCan i3 Continuous Glucose Monitor,15 Day Wear-life CGM-2 PCS

Utterly useless. I purchased 2. The first one failed after 4 days. When I started using it I checked it's accuracy against my (Sinocare) finger prick tester. The CGM showed 13.3 finger test 8.4. After 4 days it started continuously reporting extremely low readings. 3.2, finger test 5.8. Readings down to 2.2 when I know that it was ridiculous. I've now ended the first, 9 days early. Fitted the new one, following the instructions to the letter. But the app cannot find the device, even though my phone is within 6 meters, more like 60cm. I WILL NEVER BUY THESE DEVICES AGAIN. Two failed within 5 days of use and absolutely no response from Sinocare after emailing and messaging on X. Once bitten, twice shy. UPDATE: The second device finally picked up after 10-12 hours. But like the first, after 4 days it started reporting extremely low blood sugar. Check with finger prick test and it was way out. I then purchased Libre 2 sensors. So with both running the iCan device was much lower than the Libre 2. Example, Libre 2 5.6mmol/L, iCan 2.1 mmol/L. That is useless in my opinion. I have just done a finger prick test 8.1. Libre 2 9.0. iCan 4.0. How can it be 5 lower. It is wildly inaccurate. Totally unimpressive.

Sticks better than the libre and more reliable

This monitor is positioned on your belly. If, like me, you generally sleep on your front you will quickly discover a phenomenon called Pressure Induced Sensor Error. In my case this dragged my readings down well into the alarm range and made sure that on the first night wearing the monitor I got no sleep whatsoever. In the process I used the forced wakefulness to research the problem, and - fortunately - was able to reassure myself that I was less close to instant death than the gadget was telling me. It’s quite scary getting woken up by a low glucose alarm on the first night of wearing the device, and I will probably use another type if I repeat the exercise (Libre use an arm fitting site that is less likely to suffer from this issue).

No it didn’t I bought two of these costing £80 and when arrived and went to use the first one was faulty and didn’t stick to my arm so I had to open the second one and try that and again the same thing the sticky part that holds the sensor wasn’t sticky complete waste of my money . I’m genuinely annoyed as I buy these every month and have never had a problem until now!!!! I’ve contacted customer services and no reply

Brilliant service had a faulty sensor which was swapped no issues. And a lot cheaper than the others. Very happy. One minor moan it would be nice if the app could estimate HBA1C. But that is minor

Inconsistent, one sensor worked correctly, the second initially failed to connect. Then once connected gives spurious results. App is ok but would not recommend.

I am someone who rarely writes reviews. But honestly I feel compelled to do so. This product is dangerous and should not be allowed on the market. It had main grossly worried with very inaccurate abnormally high readings. I bought and tested four of these since November 2025 and I am on my fifth product now. All the time it gave me high readings. To the point I was so concerned I went and shared results with my healthcare provider thinking I may be diabetic. Healthcare provider asked for the fifth product I am wearing to do a side by side with a skin prick blood glucose monitor. I know the science behind these the readings will be slightly delayed compared to skin prick test but honestly it’s not about delay, the vast difference in readings and wide ranges. I’ve attached photos of reading I took ten minutes ago. See the differences in the reading for your self!! P.S. by the time I am posting this, it’s now 15 mins since a test. This monitor is still 9.3 mmol… a reading which would worry any normal person. This is why I say it should be banned

These work. Don't bother with the marketing of the other glucose monitors.
