The Eversense Continuous Glucose Monitoring (CGM) System by Senseonics is a unique implantable CGM device that offers long-term glucose monitoring for people with diabetes. Unlike traditional CGMs like the Dexcom G6/G7 or the Freestyle Libre, which require frequent sensor changes, Eversense features an implantable sensor that lasts up to 6 months (and up to 180 days in the U.S., or 365 days in some other countries). The system also includes a removable smart transmitter that vibrates for alerts and connects to a mobile app for real-time glucose tracking. On Reddit, where individuals with diabetes frequently discuss the latest technologies, Eversense has received a mix of positive feedback, concerns, and debate over its practicality, reliability, and accessibility. Below, we’ll break down key themes that emerge from user discussions.
One of the biggest positives that Reddit users mention is the long lifespan of the Eversense sensor compared to other CGMs. Traditional CGMs require sensor replacements every 7-14 days, which can be inconvenient. The Eversense sensor lasts for up to 6 months, meaning users don’t have to worry about frequent sensor changes. Users also appreciate the small form factor of the transmitter versus bulkier adhesive patches used by devices like Dexcom or Libre. Since the transmitter sits on top of the skin and can be removed, users find it more comfortable when showering, exercising, or sleeping. One frequent Reddit comment is that the on-body vibration alerts are a major advantage, especially for people with diabetes who experience hypoglycemia unawareness.
Despite the advantages, some users are hesitant about the necessity of a minor surgical procedure for sensor implantation and removal. While the procedure is relatively simple (typically performed in a doctor’s office under local anesthesia), some Reddit users see it as a hurdle. The need for twice-daily calibrations using finger pricks is another major pain point reported by Reddit users. This is a key drawback that keeps some users from switching. Devices like Dexcom G6/G7 and Freestyle Libre 3 now offer factory-calibrated, no-fingerstick CGMs, which users see as more convenient.
In general, comments on Reddit suggest that Eversense’s accuracy is comparable to (and in some cases, better than) Dexcom and Libre once it is properly calibrated and settled after insertion. Some users report that Eversense does better at tracking rapid glucose changes. However, others mention that early readings (right after a new sensor is implanted) aren’t always super accurate. Like most diabetes tech discussions on Reddit, the cost and accessibility of the device is a frequent concern. While Senseonics has received FDA approval for Eversense, not all insurance providers cover the insertion/removal procedures or the device itself. Users report struggles with insurance pre-authorizations and high out-of-pocket costs.
Eversense is frequently compared to Dexcom G6/G7 and Freestyle Libre 2/3 on Reddit, with users discussing pros and cons of switching between systems. Common themes in these comparisons include: Sensor duration -- Eversense has 6 months, Dexcom G7 has 10-14 days, and Freestyle Libre 3 has 14 days. Eversense is a better pick for those who hate frequent sensor changes and prefer vibration alerts, but Dexcom and Libre appeal more for those who want factory-calibrated, easily replaceable sensors. For people who: Hate frequent CGM sensor changes, Want vibration alerts for glucose fluctuations, Don’t mind fingerstick calibrations, Have insurance coverage or the ability to pay out of pocket; Eversense is a compelling option. However, those seeking hassle-free CGMs with no fingerstick calibration and insurance ease may find Dexcom G6/G7 or FreeStyle Libre 3 to be more appealing.
Eversense CGM: What Reddit Users Are Saying
The Eversense Continuous Glucose Monitoring system stands out from other CGMs due to its implantable sensor and long-term wear of up to 6 months. Unlike competitors such as Dexcom, Freestyle Libre, and Medtronic Guardian, Eversense requires a minor in-office procedure to insert and remove the sensor but offers real-time readings through a removable, rechargeable transmitter worn on the skin.
But how does it hold up in real-world use? To find out, we analyzed multiple Reddit threads discussing the pros and cons of Eversense to gain an understanding of how diabetics and CGM users feel about it.

Pros: What Users Love About Eversense
1. Long Sensor Life Means Fewer Insertions
One of Eversense’s biggest appeals is its longevity compared to competitors, which require frequent sensor replacements:
“I got tired of inserting new sensors every week or two. Eversense means I don’t have to worry about that for half a year—it’s a game changer!”
Since Dexcom and Freestyle Libre require weekly to bi-weekly sensor changes, many users appreciate the minimized hassle and less skin irritation with Eversense.
2. Accuracy & Real-Time Alerts
Some users reported that Eversense provides better accuracy, especially with fewer dropouts:
“Honestly, I trust my Eversense readings more than my Dexcom G6. I don’t get the weird false lows that used to wake me up constantly at night.”
Additionally, Eversense’s vibration alerts on the transmitter itself notify users of glucose highs/lows even if their phone is out of reach—something Dexcom and Libre lack:
“I sometimes leave my phone in another room and miss low glucose alerts. Eversense buzzing on my arm wakes me up at night, which saved me from a severe low a few times.”
3. Waterproof, Rechargeable Transmitter
Users like that Eversense’s transmitter can be removed temporarily and even recharged, unlike competitors’ adhesive-mounted transmitters:
“Dexcom glue ruined my skin. Eversense lets me take off the transmitter when I really need a break. Honestly, that flexibility is a huge plus for me.”

Cons: Issues & Drawbacks Users Face
1. The Implant Procedure is a Barrier for Some Users
One of the biggest concerns among potential Eversense users is the requirement for an in-office insertion and removal every 6 months. Some Reddit users feel that this is an inconvenience:
“I love the idea, but I just don’t want to go to the doctor twice a year for an implant. That’s too much of a commitment.”
Some also noted minor discomfort or scarring from the insertion procedure:
“It wasn’t painful, but the tiny scar stayed for months. If scarring bothers you, it might be a dealbreaker.”
2. Limited Provider Support & Availability
Because Eversense is not as widespread as Dexcom or Libre, finding a qualified provider for insertion and removal can be a hurdle. Some Redditors had trouble locating doctors who support Senseonics’ product:
“No one near me even offers Eversense insertions. My endocrinologist refuses, and the closest provider is two hours away.”
3. Insurance Coverage is Hit or Miss
Insurance coverage remains an issue. While some insurance plans cover Eversense, others do not, making the out-of-pocket cost prohibitively high for some users:
“I wanted to try it, but my insurance says it’s ‘experimental’ and won’t cover it. Out-of-pocket costs are ridiculous.”
It appears that U.S.-based users tend to struggle more with coverage issues, whereas Europeans generally report better insurance reimbursement options.
