The Stelo Glucose Biosensor includes an applicator with an all-in-one sensor/transmitter, overpatch, and Stelo app (available on both iOS and Android). The biosensor is a small and flexible wire, which is inserted by the applicator under the skin. Stelo has an expected wear time of up to 15 days* with an extended 12-hour grace period. The transmitter is connected to the sensor and is worn on the body using the patch and overpatch. The transmitter estimates the glucose values and sends them to the Stelo app via Bluetooth. The Stelo app displays the current glucose values and the direction the glucose is heading. The information can help users make better decisions about food and activity relating to their glucose management. INDICATIONS FOR USE: The Stelo Glucose Biosensor System is an over-the-counter (OTC) integrated Continuous Glucose Monitor (iCGM) intended to continuously measure, record, analyze, and display glucose values in people 18 years and older not on insulin. The Stelo Glucose Biosensor System helps to detect normal (euglycemic) and low or high (dysglycemic) glucose levels. The Stelo Glucose Biosensor System may also help the user better understand how lifestyle and behavior modification, including diet and exercise, impact glucose excursion. The user is not intended to take medical action based on the device output without consultation with a qualified healthcare professional. CONTRAINDICATIONS: No MRI/CT/diathermy – MR unsafe. WARNINGS: Choking hazard. Don’t use if you have problematic hypoglycemia. Don’t use if you are on dialysis. Don’t ignore low/high symptoms: When your sensor readings are not consistent with your symptoms, consult your healthcare provider. DON’T CHANGE MEDICATIONS: Consult your healthcare provider before making any medication adjustments based on your sensor readings. WHERE TO STORE: You can store your sensors at room temperature or in your refrigerator, between 36 F and 86 F, but not in the freezer. *A study was conducted to assess the sensor life where 77.9% of sensors lasted the full 15 days. In other words, when using the product per the package labeling, approximately 20% of sensors may not last for the full 15 days, 10% of these sensors may last less than 12 days. †Results obtained from previous Dexcom device(s) in patients with diabetes. 1 For Stelo app compatibility information, visit stelo.com/compatibility. 2 Product issues will need to be confirmed with our technical agent. 3 Validated replacements are not limited. 4 Dexcom, data on file, 2024. 5 Stelo User Guide. 6 The Stelo biosensor is waterproof and may be submerged under eight feet of water for up to 24 hours without failure when properly installed.

CUSTOMER SERVICE ? HORRENDOUS !
If I could give it less than 1 star I would. Sensor worked for only 8 days, and then gave me a “Signal Loss” message. I went through all the trouble shooting steps in the app, and checked all my phone settings. Signal NEVER came back. App says if signal loss lasts longer than 3 hours, contact customer service. I went through the app to manufacturer’s website. Customer service is an automated chatbot called SteloBot. Eventually, I was able to request chat with a live agent in the Philippines, which is also where their technical “support” is. The agent said they would request a Case ID be assigned and open an investigation, and that I would hear back in 1-2 business days. The next day, which was Saturday, I received an e-mail with a case ID number, and a link to fill out the customer service form. There was space to provide details of what the issue was as well as the sensor serial #. Before I could submit the form on Sunday, I received another e-mail saying that if I didn’t respond within 24 hours, they would consider the case closed. I submitted the form. The Stelo/DEXCOM system, acknowledged receipt of the form, and again said I would hear back in 1-2 business days. 8 days later I still had not heard back, so I again went through the Customer Service rig-a-marole, to finally contact a live agent. They were polite and apologetic,and they requested a “reinvestigation” . I received an e-mail later that day saying, my “customer service issue could not be validated” (whatever the hell that means), and that they would not replace the faulty sensor. I contacted customer service AGAIN, and asked what “could not be validated” meant. I was told the “computer investigation” said the signal came back after 10 mins. I told the agent that was not correct. The app said “Signal Loss” and the signal NEVER came back. I checked multiple times a day for the remaining time the sensor was supposed to be working. Never came back. I asked if there was anyway they could just replace the sensor anyway, and was told that it was not possible for her to override the computer’s decision. I told her once again that the “computer investigation” was incorrect, and that there was no communication between the sensor and the app on my phone, after the initial signal loss and that the signal never came back. I was told that they could not manually issue a request to replace the sensor. For what it’s worth, there also seemed to be no mechanism to attempt to re-pair the sensor with my phone, or the app installed on my phone. While it was working, the app/sensor worked okay. Be aware, the sensor DOES NOT measure actual blood glucose. It measures the amount of glucose in your interstitial fluid in your tissues, just beneath your skin. If you’re diabetic and/or need your exact blood glucose, this is NOT the device for you. I’m almost 70. Blood glucose was not diabetic level, but was higher than my doc would have liked on my last 2 physicals. My wife is an RN, and thought these might be a good indicator of what affected my blood glucose and by how much. The accuracy is roughly + or – 10%. Just be aware of that. It’s more for blood glucose trends than actual, accurate blood glucose, so if you’re diabetic and need exact blood glucose, you probably don’t want to rely on this product. The customer service for this product is EXTREMELY WEAK in my opinion. Let’s face it, we paid Amazon roughly about $110 for a two pack of these sensors. The manufacturer probably pays around $10-15 per sensor. The fact that they refused to acknowledge a faulty sensor and wouldn’t replace it tells me all I need to know. Yup, you guys got me for $110, and saved $10-15 on replacing a sensor, so in theory, you got me, ONE TIME, for $125, but I will never again by ANY product associated with Stelo/DEXCOM, and I will discourage family and anyone else who is considering it, from purchasing one of their products.For what it’s worth ; out of curiosity, just checked other reviews of this blood glucose monitor. They actually have a higher percentage of 1 star reviews than 5 star reviews. What does THAT tell you. AVOID THIS PRODUCT !!!! WOULD NOT RECOMMEND/WOULD NOT BUY AGAIN/ABSOLUTE CRAP !
Christina Ricks –
Great app and great customer experience!
I admit that when I first got this, I wasn’t sure I liked the app and I worried I would get a dead sensor and have a bad experience trying to get a replacement. After using it for a month, I can say this: I love the app and the way it reports. The graph is interactive and let’s you see your glucose readings every 5 minutes while the big number at the top only updates every 15 minutes. Someone I know with diabetes just started using the Libre 3 CGM and that app sucks in comparison. I do wish that the sensor was a little more low profile. It’s kind of bulky and with the patch you put over it, it takes up quite a bit of space on your arm. Also, my 3rd sensor stopped sending a signal after 3 hours of use and the app ended the session early. I was frustrated because I didn’t have another one on hand so I went to the Stelo website and used their chat bot to open a ticket. The replacement was approved within 3 minutes of opening the ticket with them and has already shipped. Maybe others who have had issues tried to get a replacement through Amazon, but I had no problems getting my issue resolved through the Stelo site directly. I didn’t even have to give them the lot number or my order number. All I had to do was fill out a form that asked about what happened, where I had it inserted, and when it malfunctioned. So for all you people out there worried about a faulty sensor, don’t be. The customer experience has been excellent. Just figure out how to use the app and put your sensor in the correct place and you’ll love this product!

UPDATE! Buyer Beware- support is awful!!
UPDATED 9/16Okay- it pains me to do this but I’m revising my rating. The first sensor worked great, game changer. But when I changed sensors after the first one was done I’ve had nothing but issues with the 2nd one. And it’s IMPOSSIBLE to get help!!Your forced to deal with a bot and if you can get to the point where you can actually open a case, good luck because you cannot even correspond to the email you send to further explain or provide info on th issue because it’s a no reply email?!Huh?! What kind of service is this? Zero service.I reached out to Stelo via a bot (your only option unless you can manage to get to the chat during certain biz hrs), finally got to the point where I could open a case only to be told in an email response to my case that I need to fill out some form which they never sent and then they proceeded to close my case the next day! I could not even respond to let them no that no form was ever rcvd (and yes, I check my spam/junk) …And yet I’m still stuck with a faulty sensor. I cannot even respond to the case email! It gets kicked back – so while I think the CGM as a device is amazing for understanding where your blood glucose is without pricking your finger all day (and seems more accurate too!) I cannot support a business who makes it so difficult to get help when it’s needed. I’m switching to a different company for my CGMs going forward. Sigh.I really liked the convenience of getting this CGM via Amz but it’s not worth this hassle when something goes wrong.Original!I’m working on a healthier lifestyle to better manage my blood sugar and was getting frustrated with the glucose meters being questionable when I did finger pricks. Between three different ones my b2b readings using the same finger prick would have variants of 10mg or more making it nearly impossible to determine which one was the most accurate. Decided to try this CGM and wow! Not only has it enabled me to find the blood glucose meter that is the most accurate it also helped me better understand my glucose levels after meals, exercise, during sleep patterns and has helped me stick to a lower carb lifestyle! I love seeing that I’m finally within a normal range day over day after making significant lifestyle changes!! I’m finally able to get into ketosis each day since it’s become such a great motivator to stick with that way of eating. I’m about half way through using my first of the two sensors. It paired with the app on the first try and through workouts, showers, and sleeping on my side, it’s still well intact. I purchased an additional pack of waterproof over patches that are a bit larger than the ones that come with it and I believe they have made a huge difference in protecting the sensor and keeping it in place.I’m definitely going to keep using these for the foreseeable future, at least until my next round of bloodwork in the next few months!! Im grateful to find and use this CGM w/out the added expense of a prescription. Making these more accessible is a game changer!
