Has anyone tried Sensonics Eversense CGM sensor?
I am looking for input and experience with using Sensonics sensors (good and bad) ?
I did. Trial when they were new, just one sensor. I really liked it. Loved that the sensor was inside. So swimming is easier. Exercise with heavy sweating was no issue at all. I don’t think they solved the issue of calibration yet. Every 12 hours, it’s like dexcom old days. They keep saying they will fix that, but until then it isn’t worth it.
I will sometimes calibrate my dex in the first day but not beyond that.
After they fix that and make it compatible with a pump, then I’ll do it
After 3 months the doctor needs to dig it out of your arm. I really didn’t mind this but I can see how others could see this as a red line.

Thanks, Timothy,
It looks like FDA cleared the next-generation Eversense 365 and I need to find out about the calibration.

One note on the Eversense sensor- it is not MRI safe and must be removed before an MRI.

I looked into it, but I just can’t see the appeal. It baffles me. Dexcom is completely unobtrusive to manage. (I’ve never tried Libre, but I imagine it’s similar) No doctors appointments, except to get the prescription. No scalpels. No pain. No calibration. No charging. No daily maintenance. Small. Very fast to apply…
The sensor is under your skin, but the transmitter sure isn’t. It’s the biggest CGM by a mile, too. Even bigger than Medtronic’s previous generation G4, which was decried for it’s size (among other things). It’s nearly identical to an Omnipod in size, except a little more flush to the skin.
It’s a lot more maintenance. You’re supposed to charge it daily. Gotta change the adhesive daily, too. And then there’s weekly calibrations. (I don’t actually think that’s terrible.)
The real deal breaker for me is the extraction process. I’ve read some terrifying things. The insertion isn’t too bad, but they have to cut open your arm and go fishing around for the sensor, which kinda melds into your flesh after after a while. I imagine a doctor who does a lot of these might gain some experience skills, but I certainly don’t have that luxury since I’m very rural.
The one appeal I can see is not having to refill the prescription. But I’m already getting other prescriptions and DME supplies, so adding Dexcom to the orders doesn’t make a difference.

I’ve never used the Senseonics implantable CGM. I looked at this device again since I became aware of its new one year model, the Eversense 365. I’ve watched some video discussions about this new device and I admit to being attracted to some of its features. It claims it is not subject to false lows due to compression while sleeping. My sleep has been interrupted all too often by false lows on my Dexcom G6.
The company also claims that its accuracy is especially good under 70 mg/dL. Since I target 87 mg/dL and the 65-120 mg/dl range, this feature appeals to me.
Senseonics have certified the Eversense 365 as an “iCGM” which will pave the way for future integration with commercial pumps and automated insulin delivery (AID) systems . No integration deal seems imminent and these kind of deals can take considerable time.
Senseonics has had an ongoing discussion with Beta Bionics for its iLet system. iLet is not for me due to its relatively high BG targets. There are no deals with Beta Bionics as yet announced.
Most importantly for me, this CGM System is not compatible with my do-it-yourself (DIY) Loop, an older Medtronic 722 pump paired with an app running on an iPhone. There may be some workaround using Nightscout and/or other data handling apps that I’m not aware of.
I did, however, discover that Medicare covers the cost of the Eversense CGM including the professional fees to insert and remove. Your portion of the Medicare payment would be subject to whether you carry Part B and supplemental insurance.
If Eversense integrated with a DIY Loop equivalent AID system, I would actually be a serious applicant. If the sensor has to be removed for an MRI as @Luis3 states above, that is also a serious point.

I tried it twice when the 90 day sensor was the only one available. Charging the transmitter and calibrating were not too big of a deal for me, easy to get used to doing those as part of a daily routine. There were some positives, most notably the accuracy was good and I did not have to do the “replace sensor” routine with Dexcom which can be inconvenient if a sensor dies at an unexpected time.
Another positive I enjoyed was the vibratory alerts on ones arm when not carrying my phone or any receiver. That worked great for outdoor heavy chores and sports, etc. when I did not have my phone turned on or with me. But now the G7 with direct to watch has the same capability.
The insertion/extraction is a big downside. I still have two raisin shaped scars in my arms. The first few days after an insertion the numbers are all over the place and can’t be relied on. Also, I had one sensor insertion that became infected and had to be replaced.
Overall I would probably try the 365 day Eversense if they can get it communicating with either the Omnipod 5 or a Tandem pump. Who knows if/when that will happen though.

Thanks to All for your input.
Does anyone have an inside scoop when the Freedom device will be released? A target year and quarter?
Update: I found presentation here with Freedom launch in Q4 2027.
[Senseonics Investor Presentation - November 2024]
(https://www.senseonics.com/~/media/Files/S/Senseonics-IR/reports-and-presentations/sens-investor-presentation-november-2024.pdf)
This device sound great. BUT. It’s the surgical insertion and removal process that bothers me. It is made glass and could be inadvertently broken under the skin resulting in surgery. Hoping they find all pieces.

Thanks for posting that investor report, that was a fun read. I noticed they used a codename for the sensor they are using in Gemini and Freedom, Rome2, but don’t mention if that is the same sensor they are using in the 365. Since you’ve been looking for information on this already, have you seen anything say the 365 is also Rome2?
Like other have said, the calibration requirements have kept me from trying one. I did watch another of the TCOYD videos on insertion of the Eversense - https://tcoyd.org/2023/02/watch-dr-es-eversense-e3-cgm-insertion-we-filmed-it-live/
Doing a little more digging here’s the FDA submission for the 365 including the clinical trial data. https://www.accessdata.fda.gov/cdrh_docs/reviews/K241335.pdf Values from the 365 based on the comparator values look similar to the Libre. What really doesn’t work for me is it appears to be slow to respond to changing BG. Might be due to the small study size, I really wish they’d report on 1000 people instead of 100.
