I am a medical provider who bought 2 cases of Stelo for clients in a support program that I offer. At first things were going okay, and I had an inside support person who sent a CGM or two when pairing issues became apparent. He realized that this is not a good product and left the company. When they work the way they are supposed to the patterns and information is so helpful....but when they don't, there is no customer service, no email address, no phone number. The Dexcom phone numbers don't answer questions about the Stelo CGM, so, in effect, there is not support. It is tempting to encourage people to gain this helpful information, but it is not helpful to have this level of frustration and in reality, a one star is probably too high for this CGM

The bio sensor doesn’t work!! When I called customer service they were EXTREMELY unhelpful. I filled out a form and they did nothing!! I just wasted 100$ on a product that worked for 24 hours and the customer service is so bad that they wouldn’t even help me. I have been wearing glucose monitors for months and this was the first time trying Stelo… never again Don’t waste your money!!!

Three different sensors malfunctioned as demonstrated by detailed calls and chats to CS that included comparisons to Blood Glucose readings. Readings were often and continuously off by over 100! They replaced two, but refused to replace the third and would not give me a reason why. They refused to offer advanced technical support after all reasons on the website were eliminated. I pointed out the issue is either with the device so they should replace it, or if it is user error then they should offer tech support. They refused to do either. Their support is by live chat or phone. English is not their first language and they just repeat what is on the website. I repeatedly requested higher level tech support and it never happened.

Even if you cancel in the right amount of time, they still send you one last shipment and charge you. Buyer beware - their customer service stinks! And they just want their money

ONE STAR IS TOO HIGH - RUN FROM THIS COMPANY!!! I placed what I thought to be a one-time order for Dexcom glucose sensors in July 2025 and received the product. Now, I just received another shipment for another 90 day supply. I do not need them and do not want them. I have not opened them. There is no phone number available to speak to a live person so I initiated a chat with their "bot" and was told I had an active subscription. And I was told I cannot return the products. This is ludicrous! I did not realize I had a subscription. I did not receive any recent email saying my order was set to ship. This is highly misleading and exploitative, especially for seniors who may not realize the implications of their online actions and are not even provided with a phone number to call. I simply want to return this unused product and have my account credited. I did not even open them. I am happy to pay for shipping, and they can be returned to the shelf and shipped to someone who needs them. The customer service for this company is substandard.

After using Stelo for just one month, I’m left disappointed and lighter in the wallet. The sensors stopped reading halfway through the day unless I taped them in place, which wasn’t included. The app showed random glucose spikes that made no sense. But the real kicker? I was double charged for my subscription. When I reached out, they claimed it was my fault. I provided receipts, screenshots, everything. No apology, no refund. Just silence. The whole experience screams defective hardware and zero accountability from support.

We have experienced all connectivity problems and early failures mentioned by other people. We know all about the difficulty in connecting with the almost nonexistent customer service department. But the final straw is the last batch. They are not accurate. 30-40 or 50 points off either way. Mine is running high. My wife's is running low. You cannot depend on them. We did repeated finger sticks over a period of weeks, to truth them, and they are just simply way off each time.

As many people have mentioned here, the Stelo devices seem to fail prematurely. Out of the last five I've had three of them fail before the end of their expected life. Also, be aware that the subscription service does not notify you before a new shipment is being sent. I put my subscription on pause for 90 days, expecting a a notice before my next subscription order would be sent out. I received no notice before the shipment was being charged to my card. I contacted support within 5 minutes of my card being charged, and they told me there was no way to cancel the order. That's extremely poor customer service.
