Each sensor delivers up to 15 days of accurate interstitial glucose tracking, syncing seamlessly with iOS and Android devices. Waterproof and backed by AI-driven coaching, Stelo empowers users to understand their glucose trends and lifestyle impacts with ease. The package includes two sensors and applicators, providing up to 30 days of wear time, making it a convenient tool for proactive health management. ## Description Product Description 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. If you are in or near water, your smartphone may need to be closer than 20 feet to get readings. If you are in water, you may not get readings until you get out. 7 Layne JE, et al.

STELO IMPORTANT INFORMATION: Consult your healthcare provider before making any medication adjustments based on your sensor readings and do not take any other medical action based on your sensor readings without consulting your healthcare provider. Do not use if you have problematic hypoglycemia. Failure to use Stelo and its components according to the instructions for use provided and to properly consider all indications, contraindications, warnings, and cautions in those instructions for use may result in you missing a severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) occurrence. If your sensor readings are not consistent with your symptoms, a blood glucose meter may be an option as needed and consult your healthcare provider. Seek medical advice and attention when appropriate, including before making any medication adjustments and/or for any medical emergency.

Manufacturer Contact Information Dexcom, Inc. 6340 Sequence Dr., San Diego, CA 92121 Review: 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 desertcart 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 ! Review: Informative & Underrated. - I bought this to monitor myself for diabetes, as I am at risk. The monitor is as comfortable as it can be. I believe it has improved my overall health and improved my nutrition. It’s not a live glucose monitor INSERTION is relatively painless, especially compared to finger pricking! You feel the spring action of the device quickly putting the monitor on your arm. The 10-second manual pressure after insertion, as instructed by the manual, is more uncomfortable than the insertion itself. If you’re clumsy and bump it due to bad placement or absent mindedness — it will be painful but not terribly, less than stubbing your toe. If you put lots of pressure on it while sleeping (which is mentioned in the manual) it will be similarly uncomfortable, as mentioned in the manual pressure step. ADHESIVE patch that comes with each device is sticky and leaves residue (easily removable). I find that the adhesion of the device’s surrounding tape is enough. You must place properly, thoroughly clean the site beforehand with alcohol, and leave dry for at least 24hrs for adhesive to really really work. Device typically looks ready to be removed by days 12-14. You will see it is a thin wire that is inserted under the skin — not a needle as someone previously stated. REMOVAL of device is easy; like taking off a bandaid. LIFESPAN is typically 12-14 days. I usually remove by day 12 or 13 if I’ve been in the pool or had a particularly sweaty week. The APP is intuitive, especially if linking with Oura ring/app. The device updates to the app every 15 mins, with 5 min increments being monitored but only reported when synced during the update. Again, it is not a live glucose monitor. The AI used to help report nutritional information when logging a meal, can be unreliable and needs your review. Should be approached more thematically, I think. By using this device I have learned what types of foods/meals lead to spikes in my blood sugar and am able to plan accordingly. I will be buying more and more. ## Features - ✅ For people NOT using insulin, ages 18 years and older - ❌ Don’t use if: On insulin, on dialysis, if you have problematic hypoglycemia, are modifying medication without HCP consultation, or if you have a history of eating disorders - YOUR SUCCESS, OUR COMMITMENT: Should you experience an issue with your biosensor before its 15-day wear is up,[2] we’ll replace it for free.

Stelo measures glucose in the interstitial fluid just under the skin, while a BGM measures glucose in a drop of blood. **Q: Where can I find support for Stelo product issues?** A: Product support and replacements are provided by Stelo. If you experience a product issue, request support through the app: tap Settings>Contact>Continue, select the message icon to chat with SteloBot, and follow the prompts for “Report an issue.” **Q: What does “Session Ended Early” mean?** A: This means your biosensor can't determine your glucose level. Follow these tips to help prevent it: apply the overpatch, keep it dry for the first 12 hours, gently pat it dry if it gets wet; if it peels, trim the edges and secure with medical tape. **Q: Why is there blood around the sensor site?** A: For the insertion needle to reach the interstitial fluid (where it measures the glucose), it must penetrate the dermis layer of the skin, which has blood vessels scattered throughout. Penetrating the blood vessels can cause bleeding. ## Customer Reviews ### ⭐ CUSTOMER SERVICE ? HORRENDOUS ! *by T***F on August 26, 2025* If I could give it less than 1 star I would.

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! ## Frequently Bought Together - Stelo Glucose Biosensor & App by Dexcom—A Leader in Continuous Glucose Monitoring (CGM). 24/7 Glucose Tracking & Personalized Insights to Reveal Patterns. 2-Pack (Up to 15 Days Each). iOS & Android. - Skin Grip Adhesive Patches Compatible with Dexcom G7 & Stelo CGM – Waterproof & Sweatproof Cover for Continuous Glucose Monitor Sensor, Stays Secure for 10-15 Days – 20 Pack, Tan - Onida Dexcom G7 Adhesive Patches 20PCS,Waterproof Over Patches for G7 & Stelo Flexible CGM Tape,Pre-Cut Adhesive Medical Tape, Continuous Glucose Monitor Sensor Cover --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/709297153-glucose-biosensor-and-app-2-pack-up-to-15-days](https://www.desertcart.es/products/709297153-glucose-biosensor-and-app-2-pack-up-to-15-days) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-08-21*
