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

I had this problem when they first came into use, this might sound daft but are you placing it in the right area? Even now I sometimes place it incorrectly and it will start up but then fail.
 
Well I am placing it in the same place as I did with Libre 1 sensors which I never had a problem with until I started using the LibreLink App

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’ve been using them for several years. Most of them last the full length of 15 days, or 14 days on the older sensors. The only problem I get occasionally is either the sticky back fails and the sensor falls off, or I hit a door frame accidentally and it’s ripped off. I’ve had about two fail due to hardware failures. But, you can always get the sensor replaced if you inform Libre. They will just send you a new one. So mostly, they are extremely reliable.

What phone do you to communicate with the sensors, and how do you find the sensor values compare against finger prick tests?

I had to stop using mine as three times a night the alarm sounded …. Thought ah! bSL needs checking….NO …. MSG said Signal Lost !!!!! So with already having to get up three time a night for the toilet due to the new Dapoglifazin drug for my CKD I was getting about an hours sleep a night! Now given up !!! Liver never answers my questions!

I’ve got an iPhone 16 Max Pro. I don’t bother with the finger pricks anymore because I found the sensors easily good enough. HbA1c Tests are pretty much spot on with what the Libre predicts. I’m about to go onto a close loop insulin pump so will be coming off Libres. It’s a shame because I found them to be very good but unfortunately my pump won’t support them and uses its own type of sensor.

Abbott are very good at replacing any sensors that fall off or fail before the expected end date. For the most part over the last year and now with the Libre 2 Plus they have been fine. I don't like the 15 days though, before they always ended on the same day I started them, now it's uncertain exactly when they are going to finish so you have to plan ahead.
Talk to Abbott, they are usually very helpful.

Thanks, interesting (and I'm pleased) that they work well for you. Good luck with the pump/new sensor combo too.

This is similar to what I see. It seems to be dependent on the sensor, or more probably on the sensor location. My working theory is that these ones are too close to the muscle (I don't have much fat on my arms so the available location is pretty small and I try to move it a bit between sensors to avoid aiming for exactly the same spot!)

I alternate between left and right arms and also upper and lower. So: 1) left arm, just below shoulder; 2) right arm, just below shoulder; 3)left arm, just above elbow; 4)right arm, just above elbow.
Thus, each general location has 8 weeks between use. So (even if I somehow manage to hit the exact same spot) plenty of recovery time.

Yeah it's like a gamble with them sometimes, I'd say nearly half of my sensors always have tons of sensor errors at inconvenient times. Maybe I'm doing something wrong idk :arghh:
 
As an update..... I have found a way of getting the "dead" sensor, 365 error, alive again.....I won't say how, because Abbott won't like it.
So I got a "dead" sensor, 365 error, replace sensor, today, it was within 24 hours of starting it up, I did "some steps" and then scanned the same "dead" sensor again..... and now the sensor works again. So this proves to me that there aren't problems with the sensor, it is the LibreLink App that doesn't work correctly. Unfortunately I have told Abbott several times that their LibreLink app has a fault, but I find Abbott are too arrogant to listen.
 
This is after the "Replace Sensor Message"?

I must admit that I've never tried as I tend to just get on and replace the sensor at this point (they are usually suffering from some other ailment so I'm happy to get an automatic replacement), though I could imaging that if the sensor itself starts working again (producing data and still within the 14/15 day lifespan) you can likely pair it with e.g. Juggluco even though the Librelink app has declared it dead and decided it's not interested in connecting again.

Yes I’m self funding and have had 3 fall off I’ve today gone bk to finger pricking I’m type 2 on insulin
 
A T1 and been on Libre 2+ since it's release in April/May and only had a couple that have lasted a full 2 weeks, the reset keep being getting faults after about 5-7 days in, and Abbot kindly keeps replacing them, funnily enough they'd nearly perfected the Libre 2 and that was being nearly same as finger pricking, but the 2+'s they vary quite a lot between 2 - 8 sometimes, luckily the CGM is always lower than the actual blood tests.
Abbot reckons the 2+ and 2 should both be the same apart from the 2+ being more accurate
(LOL) and more resistant to coming loose (this is true), what I get sometimes in bed is
reading from CGM of '2.4' (I've given-up on the alarms from Libre as they seems to be inaccurate) so decide to go downstairs to do a blood test, which shows I'm 8.

Wondering if it's an age related things causing all the variations as I'm 68, I use it in conjunction with the mySugr app which has really helped by insulin dosage.
