I would not recommend this product!! It has been constantly +50 points different. I can't trust this product. They did replace one sensor but it performs the same way. I am going with a different product. The only reason I tried this one was because I was having trouble getting a prescription for another one. Don't waste your time and money. Get a prescription and use something different!!!!

If you're considering using guest checkout, think again. My package arrived with sensors that wouldn’t calibrate, and since I wasn’t logged in, they refused to help or refund me. There was no accountability and no way to escalate the issue. It felt like they were just hiding behind “policy” walls.

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.
