I didn't even realize that I had signed up for a subscription (found out via an email saying my order was being processed.) I cancelled the day I found out and they processed anyways and will not give a refund.

If I could, I would give it 0 stars. The product has worked very well for 8 months and I was pleased. It provided the information I wanted. I am a retired RN that worked with diabetic patients. I am knowledgeable about finger sticks and also CGM. I had a sensor that failed to pair and they asked me to buy a new one. I had another on hand and used it. My readings were not as accurate as they had been for the previous 8 months. The difference between FBS and CGM reading was significant. Yes, I know they are not the same but they should be fairly close not off by 50. I know that my CGM should not CONSISTENTLY be “124” for days and days with any fluctuation. I thought the issue might be with this lot of sensors. As I am a nurse and have done device R&D, I thought I would report the failed sensor and the unusual numbers. That is where the nightmare began. You have to use their ChatBot. I did. The next day I received an email asking for more info. I responded. In response, I received 3 emails telling me how to do a fingerstick/how to apply a CGM and explaining the difference. The emails they send all arrive twice into my in-basket which was annoying. Now they want me to complete a form. I am happy to do that. I had a question so I tried to reach out using one of the email addresses they had used to send me emails. Apparently all of the emails they send out are “NO REPLY”. The response I received to my email reads “You cannot reply to their email as you do not work at the company and do not have a Stelo email address”. So, I go back to the email asking for more info thinking that will work…NO! In a matter of 12 minutes, I sent the same inquiry via email 5 times and received the same “you don’t work here” email. Their suggestion was to call the person I am trying to reach at Stelo.com on the phone and ask them to request I be given access to send emails. Really! My only recourse is to go back to the ChatBot! No way. Their customer service is horrible. There is no customer service in my opinion. I want a replacement for my sensor that would not pair with my phone. After that, I will consider keeping my subscription or not.

When it works, it works well. When it doesn't, they will screw you out of a replacement when possible. I had one that never linked to the app via Bluetooth, even though it searched for over an hour, and I followed each of the suggested steps to connect it. Gave up and used a new one, which worked right away. I filed a chatbot ticket for that sensor, and they said I "qualified" for a replacement. That replacement arrived a few days ago. Literally, the next day, the new sensor that replaced the old one stopped sending readings. After only 5 days of use. I waited about 12 hours, gave up, and used yet another sensor. I filed another ticket, and this time I was "not eligible" for a replacement. WTH!?! I have to eat eight unused days of a sensor (MONEY!) because of . . . why?! That chatbot is useless. Will call them tomorrow (only available during regular business hours) and see what they say. However, based on these last two sensors, with only five working days out of the expected 30 days, I wish I had a better alternative (I don't qualify for a "real" Dexcom). That's a lot of money out of pocket. Product quality is going downhill. I have had sensors fail in the past, but like once a year. Not two in a couple of weeks! Ugh . . .

What an absolute crap product - I bought this via Oura ring and the first sensor didn’t work - the second sensor broke off into my skin and wouldn’t connect - I ordered another pair and they sent it to a random address that I cannot change. Shit product and now I appreciate why their stock is down. They will bring Oura down w them.

Customer care is non-existent! I wanted to talk to a human, but it doesn't appear one exists in this company. My sensor failed after 3 days, so I replaced it, and the latest one started to warm up and failed immediately. This is where I tried to speak to a rep. who could/would assist me. Unable to find such a person in this company! I am done!

About 5 days into the 15 days...the readings seem to "flat line" at a minimum of 130ish. I'd prick my finger and get a reading of 98, 102...and the app says 138. Was told "compression" could be the issue when I sleep on my side. They replaced the first one....good for them...but it happened a second time and they for unknown reason didn't replace it. I could still see what spiked and didn't spike my readings....but the actual numbers were bogus.

My experience is that this sensor is unreliable, inaccurate, and backed by awful customer service. I write this review as I wait for a supervisor to help figure out why it's been two weeks since I filed a product complaint with Stelo, actually three complaints, which have not been resolved. I’ve been using this sensor for eight months, and honestly, the only thing consistent about it is its consistently poor performance. What’s most frustrating is that these problems aren’t one-offs—they keep happening, over and over, despite my best efforts to make this product work as promised. Reliability and Sensor Failures: Time and again, the sensors fail long before the advertised 14-day lifespan. I’ve had them stop working after just a few days, and even receive some that were dead right out of the package. It’s maddening to pay for something that doesn’t even make it halfway through its expected life. Accuracy Concerns: The readings are all over the place compared to my finger-stick tests. Sometimes they’re noticeably higher, other times much lower. This isn’t just annoying—it’s dangerous. I rely on accurate glucose readings to make decisions about my health, and this inconsistency creates constant uncertainty and anxiety. Poor Customer Service: Dealing with Stelo’s customer support is almost as bad as dealing with the faulty sensors. Reaching a human being feels like a miracle. The chatbot is useless, the responses I get are generic, and follow-up is rare—if it happens at all. I’ve had to chase them down for replacements, and even then, the process drags on unnecessarily. Connectivity Issues: Just when I start thinking a sensor might last, it starts dropping the connection to the app—especially toward the end of its life. I’ve had to restart the app, re-pair the sensor, and sometimes just give up entirely. I wanted this to be a reliable tool I could trust. Instead, it’s been a constant source of frustration, wasted time, and unnecessary stress. For a product that plays such a critical role in health monitoring, this level of failure is simply unacceptable.

Stelo is a nightmare! No customer support AT ALL ON A PRODUCT THAT HAS A 2-WEEK LIFE SPAN. It wouldn't pair on the 1st one-in the trash after 5 days. The 2nd one lost signal with 8 days left and no customer support would help me. I just went round and round with a bot and got nowhere. Finally threw the 2nd one out today. ALL I GOT WAS HIGH BLOOD PRESSURE...FORGET ABOUT GLUCOSE! I bought through Oura to use with my ring. Biggest mistake ever!
