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.
Original price was: $99.00.$86.16Current price is: $86.16.
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 Dexcom, data on file, 2024. 3 Stelo User Guide. 4 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. 5 Reed J, et al.

Not returnable, Can be painful, won’t work with Android 11
This product can be painful to wear, depending on where you put it. This is especially true if you are skinny and/or muscular and don’t have a lot of fat on your upper arms. If that’s the case, be sure to put the sensor between your deltoid and your tricep muscle which is around towards the back of your arm, closer to your shoulder than your elbow. I mistakenly put the first one too close to my elbow and experienced shooting pain anytime I moved my arm in the wrong direction. After a day and a half, the pain was too intense and I had to remove the sensor. However, I put the next sensor higher up on my arm between my deltoid and my tricep and then it was fine.Once you do install the sensor, DO NOT THROW OUT THE BOX OR THE APPLICATOR, even though the instructions specifically tell you to throw away the applicator. This is because the serial number is on the applicator and/or the box and if you have any trouble with the unit, you will have to provide the serial number or Dexcom will not help you.If you experience any kind of pain, DO NOT TELL DEXCOM THAT HAPPENED. Once they know you have experienced pain, you become a liability to them and they don’t want you as a customer anymore. At that point, they will not help you, they will not offer replacement sensors and they will not offer you any refunds. If you have to take a sensor off because of pain and you want a replacement, you will need to make up a story when you contact Dexcom. I recommend simply telling them that fell off, as other reviews indicate Dexcom will generally offer a replacement if the sensor falls off.Finally, the website does not bother to tell you that this product will only work with Android 12 and up. If your phone does not meet those requirements, then you are out of luck because you can’t return the product. I eventually solved this one by upgrading my phone, which I probably needed to do anyway, but I didn’t appreciate getting forced into it.

It works and it is accurate.
I must admit, I messed up installing the first one. So it did not work at all. I will take that as a learning curve since that was my first time using anything like this. However, when I installed the second one, it was very smooth. I downloaded the app and paired it up with my Bluetooth. That was when I started receiving messages from the device. After the warming-up messages, I started receiving real-time data from the device. I have had three showers since I installed the device, and it continues to produce the data I need to manage my blood sugar accurately without a prick—wonderful and amazing device. It works, folks.

Overall happy with the device
If you need a CGM for diabetes I would use whatever device your doctor recommends. I have worn this for a day and it has already stopped reading twice and says “Brief Sensor Issue” with a note saying it could take up to 3 hrs to start reading again. I have attached pictures. It did start reading again soon after.Update: After wearing for a few weeks I have noticed that it works decently but it tends to be off by about 20 or so on the readings compared to a glucose meter that you prickly your finger. Just be aware that the numbers may be a little skewed. I will continue to use and buy again.It seems to be decently accurate if your someone who is just curious of your glucose readings. I have compared readings to a stand alone glucose meter that uses blood from your finger and they are only 4-7 mg/dl apart.This only goes down to 70 and beyond that it doesn’t give a number. I would like to see how low my level gets.I read reviews prior to purchasing. I took the advice of many people who bought this device before who stated that the adhesive patch was garbage so I purchased a package of adhesive patches that got good reviews to go along with the device.So far the sensor has not fallen off and overall I am pleased with it, keep in mind I do not have diabetes nor do I wear this for medical purposes. I am more curious on how my body reacts to certain foods and when I’m sleeping.I have had no issues with the app. 4 stars since it has” sensor not working” issues twice within a day. Overall I will continue to use and would buy again for my purposes.

Only works half the time
This is the first time I’ve used a CGM and Stelo. It’s a great tool when it works….but it only works half the time. The first day of the first sensor was completely inaccurate. The readings were all over the place – over 250 and under 70 within a couple of hours all day. If that was what my blood sugar was really doing, then I would have felt sick and that was not the case. Day 2-8 readings were accurate, showing gentle ups and downs as is normal depending on meals, exercise, etc. About 10:00 pm on day 8, I received a message that the sensor session ended early and I would have to replace the sensor. In essence, I only got 7 days worth of readings on a 14 day sensor. For $50 per sensor, that is a very poor value. In addition, throughout the entire time I wore the sensor, the sensor would experience “Brief Sensor Issue” messages, which meant the sensor was not registering readings. This would happen about 8-10 times per day. ‘m older and have thin, crepey skin on the back of my arm. When taking off the sensor, I had to be very careful that I didn’t tear my skin. The adhesive is very sticky and it was difficult to remove. I do have the second sensor so I’ll give it another try but so far I don’t think it’s a good value for the price.
