Stelo Reviews 202

UPDATE 1/8/2026 I had a nice conversation with both dexcom and stello about my problems. They were happy to send replacements but I did not want to continue with the system. I realize I had different expectations of what the CGM does and how it reads. I think ultimately the advertising for it's use lead to this. Customer service from both companies was excellent and educational. I think this is the greatest benefit of using this sensor is education on blood sugar and it's effect on the body. I feel some of my frustration has to do with hi tech items can sometimes not work as planned. For instance two out of four sensors did not pair and that can happen. I want to stress I learned a lot about BS and think the system does work, it is just I was expecting different expectations and I will now reevaluate. AGAIN BOTH COMPANIES WERE VERY SUPPORTIVE AND HELPFUL AND FRIENDLY with advice to help me on this journey of health and wellness.

Two out of six sensors did not pair. Another two gave bad readings all the time (confirmed by standard glucose monitor). Two sensors were not accurate for 40% of the time (confirmed by standard glucose meter). This system measures glucose in interstitial fluid, not glucose in blood. According to Dexcom, this is for lifestyle use, so not really medical use as it is not really accurate all the time

The patch falls off. When it does not fall off, it stops working well before the end of the payment period. We have used it for four months and will not continue as the daily cost is quite high given the fact that we are only getting about 40% of the paid-for time.

VERY DISAPPOINTED for a product that is EXPENSIVE and being used to help me STAY ALIVE. All four of my sensors failed in one way or another. The company is horrible. You talk to chatbots and there is no record of your chats. Find a different CGM company if you don't want to be stressed out and therefore raise your blood sugar just from trying to use their product!

Received two sensors that wouldn’t activate. I followed the setup exactly as instructed, but both failed within minutes. Their return system is useless, and support is just a formality no one reads the messages. Basically spent $100 on dead sensors.

I have tried multiple times to purchase, the website has a glitch and says the address doesn't match the credit card. I have tried multiple cards and FSA, cannot purchase. I could never talk to a live person. Last time, the bot told me to buy from Amazon, at a higher price.

The stelo sensor doesn't work 50% of the time. You will be lucky if you get a replacement for one - I bought 6 in a batch and 4 failed. They replaced one. So I lost $120 (3 x $40).
You can't talk to someone on the phone. Chat only is available. Good luck with chatting with overseas customer service reps, begging for a replacement.

Glucose readings are off by 50+ mg/dl when compared with a finger stick test. No customer service is available to fix the issue.

My arm start bleeding after I applied the sensor and the bleeding would not stop. I tried to call Dexcom customer service but it does not exist. Chatbot was no help. The reply was that I will get an email within the next to 24 hours. I removed the sensor and applied pressure pad to stop bleeding. The next day I got an email stating that if the bleeding continues install new sensor (easy for them to say, new sensor cost $50.00 and they did not offer to send a replacement) and go to emergency room if bleeding does not stop.

Sensor stopped working after 3 days. Customer service would not replace, no explanation as to why

I wish I could give zero stars. They are scamming people. They take your money, do not deliver, and then tell you that company policy prevents refunds. Stay well away from this company.

I am very disappointed with Stelo, Despite the company’s claims of high accuracy, my readings were inconsistent and often didn’t match how I was feeling or the results from other devices. I double-checked my technique and followed all instructions, but the numbers still varied much more than they should. For a device that’s supposed to help manage blood sugar reliably, accuracy is critical, and this monitor simply didn’t live up to the promises made in the marketing. I would not trust it as my primary glucose tracking tool.

I'm 3 1/2 weeks in to using Stelo. On my second Stelo CGM. For me it's all been positive. I haven't had any problems and haven't had to reach out to customer service. I I love having the feedback. I'm learning so much. It's life changing for me. And, the best part is that I didn't feel the insertion at all either time. I've already bought another month's worth. I only wish they were cheaper. If they were, I'd keep using them for a longer period of time. Also I found it definitely easier having someone else do the insertion and taping. It was challenging to do it all by myself.

I got a new one, only one patch for 15 days, the first morning gave me a reading of 154mg/dL, I tested my sugar with more reliable machine and came out to be 104mg/dL, that is about 33% error, I threw it away immediately :)

When you call for customer support, you obviously get a Third World country where the people read from a script if your question is not on the script, they don’t know what to say to you… The customer…you are not important. The English is very hard to understand and I was an English teacher. When asked are you in India or the Philippines they respond——We are offshore so they won’t tell you where they’re located so after you buy a Stelo—you-the customer—have no value. Going to look for an American English speaking support company.

Stelo glucose monitors are NOT reliable. One monitor failed reading after 5 days of use. Then 2 of them consecutively failed to pair with my phone ( and I have used them in the past)… so sadly, customer service don’t help at all, they just ignore your emails and texts, no reply whatsoever. Very bad, bad service and monitor as well…Do Not Buy them…. Save your money….

I’ve never experienced customer service as unhelpful as Stelo’s. The glucose monitor itself may be fine, but the support behind it is absolutely not.

I had issues with my subscription and needed to update my payment information—something that should be simple. Instead, I was repeatedly told they couldn’t help me and offered zero real solutions. After going in circles, their final answer was essentially to order somewhere else.

It’s unacceptable for a company selling health-related products to provide no way to manage basic account or subscription settings and then dismiss customers when they need assistance.

If you’re considering Stelo, be aware that their customer service is not equipped to support you when anything goes wrong.

One sensor seemed to give fairly accurate readings, but didn’t even last a week before coming off. Stelo did send a replacement. The next sensor gave wildly inaccurate readings. Random spikes of 50mg/dl or more (in fasted state) the readings were very inconsistent with what I know my bg to be and with the previous sensor. The first one was helpful to see trends, the second completely unreliable. I have one more in my pack… tbd. Overall I would not recommend paying for this product.

I was an early adopter of Stelo and had very high hopes since I hate sticking my fingers so much and don't qualify for a CGM from my HMO. The first few months worked out okay, though the sensor seemed to report much higher readings than that of a finger stick. I got used to that and worked around it, and still ended up staying in range most of the time. I also had a couple issues with sugar dropping, and the Stelo would say I was in normal range, but I was in fact a lot lower. Stelo just said that their product is not designed for that type of event and pointed out I should not be using it if my sugar goes low at times.

Stelo\Dexcom does not offer any real customer service, so the feedback I gave was via the App Store and attempts were made to use the AI Bot ("SteloBot") on their site, which is pretty useless.

I was on the three month subscription plan to minimize costs as best possible, but noticed more and more frequent sensor failures. My last batch had over a 50% failure rate, well before the two week sensor lifespan was up. I finally gave up trying to haggle with SteloBot and canceled my subscription. I ended up getting stuck with five bad sensors, pretty expensive.

It's really too bad, I was hoping that Dexcom would demonstrate better quality control and offer much better service since they are already well established in the diabetic support market. I tried to get refunded for the last batch of sensors that failed but was told by their AI Bot that I wasn't using them correctly. I used the product from launch up until recently which is just over a year so it's not like I gave up easily and I was very careful with the sensor application and use due to the high cost.

If Dexcom really is interested in offering a better product their manufacturing controls need significant improvement, and the App needs to be truly supportive of type 2, non insulin dependent diabetics. The few times I actually got feedback from Dexcom's app team I was just told that the product is not intended to support diabetics with medical decisions, it's more of a lifestyle product. Pretty poor response if you ask me.

No human help, no meaningful troubleshooting, only repeated FAQ links. This product clearly isn’t ready for real use.

I inserted a new sensor and it started bleeding heavily to the point that I had to remove it and seek medical help. When I contacted Stelo, they simply said, "We're sorry, but you should insert a new one!" That's shameless!
