Anyone having big reliability issues with Freestyle Libre 2 Plus sensors?

[MuttNJeff]

For me, about 50% of the readings have been way above the fingerprick (if above range), or severely below if below range. I do not use Abbot blood meters/strips (had a bad experience years ago, go new batch of strips, almost noe worked)

I've also given up on the alarms - if it wakes me up, either I was actually ok but then had to spend hours getting back to sleep, or else I was low but it took so long to record the effect of the dextrosol tablets that I could not reinstate the alarm except at a stupidly low level.

For me, a reading of perhaps 6 or 7 could be a good time to look at the graph and maybe take more (slow-acting) carbs, but you cannot set the low level that high.

And I cannot see the point of setting a high-level alarm for a type 1 : if I'm having to go for a #1 and generally feeling hot then I know I'm high without an alarm.

So I have been using Libre 2 for a while now and haven't had 1 sensor last 15 days. They have lasted between 8 hours and 11 days at best. I have found them very unreliable. Has anyone else had this issue? Does anyone know why these sensors are so unreliable?

I am absolutely astonished at how far off my finger sticks are from the CGM reading with the FreeStyle Libre2 plus. I have had it for at minimum one year and completely trusted the readings. In 2024 I was pregnant and per my CGM my blood sugars were great. Unfortunately, one week before my daughter's due date she passed away. In the hospital my A1C was 10 and the free style reporting system estimated me to be in the 8 range. My sugars postpartum and grieving were all over the place per my CGM then my MD put me on a long-lasting insulin in addition to being on the tandem pump. In Jan my A1c was down to 8.5 and since then per my CGM my sugars have been the best they've ever been. Yesterday I excitedly had my A1C checked and to our surprise my A1C was 9.1 so the nurse did a finger stick, and I was really 319 while my CGM was reading 170. I went on comparing finger sticks to CGM readings and how far off they are so scary, and I can't help but think if i didn't have this CGM on and just did finger sticks during my pregnancy my daughter would be alive and well. I called Free style was transferred a bunch of times and no one cared all they said was we can replace your sensors. What a downright awful company!

Hi Pipp,

Yes I have contacted Abbott about this, but I find a 100% failure rate of the Libre 2 plus unexceptable. Libre 1 was a lot more reliable... I know it has been around for a while, but the Libre 2 appears to have been put to market too early and the LibreLink App needs to be tested properly.

I have even offered my services to Abbott although I am sure they won't do anything, but I have 20 years of software testing experience and can see several problems with the App and Libre system. I have identified several cases where the LibreLink App fails, but the sensor doesn't, just the LibreLink App stops reading the sensor.

I can understand this. We have just got a Libre 2 + for my husband and in the last 48hrs all we have done is constantly scan it because it’s not staying connected to the apps, now it’s saying things like “this service is not available” and “no connection”. It’s the first 2+ and it’s just stressful. It also won’t linkup when we do manage to get it to read the sensor (which seems to be working) so I don’t know what his blood sugars upto (he’s only just been diagnosed and we got no information at all so I have been trying to learn about it all on the hoof).
Eurgh, at least I don’t have to stab him all the time
Take care

Yes.
Had the Libra 2 for a while now, Moved to the 2 Plus on the last prescription and so far the first one just stopped working, one fell off (I've never had that before) and this one looses connection quite often.
Abbots have kindly replaced both.

I'm a Libre 2+ user and find it okay.
It's in a hybrid closed loop with omnipod, which I change every 48-60 hrs (rarely last to 60) If any problems occur its more often than not a fresh omnipod cures it.

I do have to wear both devices very close together, on the same arm so that's a nuisance. In warm weather, if working hard outside I have some additional self adhesive patches but haven't used these for ages. The latest adhesive backing seems very sticky indeed, I do wear a protective armband though.
