One out of four sensors that I had received worked. Their customer service was helpful, but a bit slow and delayed in their responses. One of the devices wouldn't pair at all with my phone and two lasted 3-5 days. Whether or not the readings were accurate is difficult to tell without comparing the readings with a valid source, but I could see changes with specific things that I consumed. The product just doesn't work and at $25 a device, getting a 75% failure rate makes these not worth the hassle.

I’ve had an issue with each and every Stelo bio sensor I’ve used and it was something different each time.. complete waste of time and money. I would not recommend this product.

Disappointed: Inaccurate Readings & Devices Failing Within days
I wanted this to work. I really did. But after going through three sensors, I can't recommend the Stelo by Dexcom — at least not in its current state.
ACCURACY ISSUES
I consistently cross-checked my Stelo readings against traditional blood glucose strips, and the CGM was off by 10–30 points on a regular basis. More alarming: overnight, the device repeatedly showed me hitting hypoglycemic levels as low as 38 mg/dL — which simply was not happening. False low alerts are not just inconvenient; for anyone managing their glucose seriously, they're genuinely stressful and potentially dangerous.
DEVICE LONGEVITY — FAR SHORT OF 15 DAYS
Dexcom advertises the Stelo can last up to 15 days. Here's my experience:
• Sensor 1: Failed at 6 days
• Sensor 2: Failed in under 24 hours
• Sensor 3: Failed at 2 days
I even purchased an overcover specifically to protect the sensors and extend wear. It made no difference. To Dexcom's credit, they replaced my first failed unit at no charge — but I didn't bother submitting the other two.
SUBSCRIPTION & REFUND POLICY — BUYER BEWARE
This is where I'd urge the most caution: the subscription auto-renews, and Dexcom does not allow returns for a monetary refund. Make sure you fully understand what you're committing to before purchasing, because if the device doesn't work for you, you have very little recourse.
I hope Dexcom addresses these issues. The concept is great — the execution, in my experience, has been a consistent letdown.

Plan on spending a half hour a day restoring its connection
Connectivity is unreliable. I bought two to try it out. The first one started dropping the connection after a week. A couple of days later, it wouldn't connect at all without manual re-pairing. It is important to note that my phone is seldom more than a couple of feet from my sensor, either in a pocket or on an adjacent table. Stelo support said they would send me a replacement. Since I had already bought a second sensor, I followed the procedure below which got all the data off the old sensor and replaced it. The new one connected intermittently, then quit. With a third sensor on the way, I may have a total of 3-4 weeks to decide if getting the data a few times a day is worth the cost.
The procedure (Android): Force stop the app, open Bluetooth settings, "forget" the Stelo (DX....) and shut down Bluetooth for about ten minutes. Then restart Bluetooth, manually add the sensor, start the app, then wait for the phone to confirm that I want to pair the device. Bingo! Another one or two retrieval cycles before it loses the connection again. The device seems to store several hours of data until it can send it to the app, so I've lost very litte data, just time.
If Abbot ever gets the Libre Rio to market, I'll be their first customer. Until then, Stelo does help me manage my diabetes without medication.

Disappointed in the STELO product/customer service
Disappointed in the STELO product and customer service response times. The website provides no clear way to reach customer service and all you get are auto replies. I pay $90 per month out of pocket and last month I had 4 full days with no connectivity or spotty at best, which defeats the entire purpose of wearing a CGM. I am cancelling my subscription as soon as I find a replacement. If they aren’t going to take care of their customers who are on the subscription, then I’ll take my business elsewhere.

Inorder 4 sensors only one out of the 4…
Inorder 4 sensors only one out of the 4 worked and only 10 days. The second sensor could not pair. The 3 sensor fell after 2 days and the 4 sensor could not pair on day one.
Pls avoid stelo, I have used free style sensors before so I consider myself a pro using them. I never had so many issues with their sensors. Stelo doe not work is not a user issue is a machine issue.

The Stelo product is seriously lacking
The Stelo product is seriously lacking. I'm a diabetic and it is critical to know the actual value when my blood sugar is Low, yet the Stelo app can only tell you it is below 70. Well it makes a BIG difference and this should be fixed. Also their 24/7 Bot support is WORTHLESS. It can NEVER address my questions or issues. I used a Dexcom G7 before, but Stelo is a BIG letdown. I used to be able to get my glucose readings on my Smart watch, but Stelo only shares if you have an APPLE watch. Will this ever be enhanced?
