I have used the Libre2 for just 4 months and have had constant problems. Worked fine for 1 month then had 5 failures in a row, however, Abbott sent replacements; but again, one worked and now 2 have failed. Going back to sticking my finger. Just too frustrating with failure after failure. Who is paying for this? Medicare is being ripped off.

Sensor stopped working after 5 days, changed it and new sensors did not work. Spoke with many people at FreeStyle Libre systems and uninstalling APP and reinstalling did not work either. Have tried 3 different sensors after phone updates and still not even reading to start the sensor. Now, nothing scans. All my systems are updated on my phone and still nothing scans. Please advise.

Having big problems using Nova Rapid Insulin and Lantas Insulin not working correctly even when Increasing NR Insulin and tests remain to increase without any further intake of carbohydrates. NR Insulin is taken with all meals with adjustments for Carbohydrate Intake, Lantas taken only at Bedtime. Readings are correct monitored by separate test, however insulin not acting correctly.

App is not functioning at all (on Iphone). I press the Check Glucose button and it recognises the click (the button changes color) but the scanner doesn't open so I can't get any readings.

I have issues with more than 1 out of 3 sensors, I would say. This is insane. I love the product, when it works, but...there are so MANY issues. It's so unreliable.

I've only been using the FreeStyle Libre 2 for two weeks now. When it was time to replace the sensor I was unable to get the second sensor in the kit to load into the sensor applicator. I noticed the blue sleeve around the edge of the sensor applicator was still depressed into the applicator base so it would not go down far enough in the sensor container to capture the second sensor. I called tech support and was told they were sending me a replacement and that I will need to send the malfunctioning kit package back to them. I took my second package, opened it and as with the first kit. I was able to get the first sensor to load into the sensor applicator and attached the sensor to the back of my arm. I inspected the sensor applicator and the blue sleeve around the edge of the applicator was recessed within the base of the assembly. My thought is that the blue sleeve is the actual part of the applicator that grabs the sensor and sense it is recessed the second sensor in the package can't be grabbed. The Abbot folk's solution is to send you a new package and have the customer send back the faulty package. If I have the same experience with the next sensor change in two weeks, I may consider using some other CGM.

I received the dreaded "Scan Error" message multiple times. When my wife scanned it from her phone, that made me think it was not the sensor but the phone. So, I turned my phone off completely, turned it back on, and . . . it worked! Maybe the sensors aren't bad; the program is glitching out.

I'm on my third sensor, and the first two worked perfectly well, although the numbers were consistently lower than my finger stick reading (I don't know which is off--why would I suppose it was the finger stick that was accurate?--I don't know. I needed to turn the "signal loss alarm" off (under the heading alarms) because it was waking me up at night. When I woke up to handle the situation, everything was fine--just had a "signal loss" alarm waking me. I went from back-of-the-arm on the left to back-of-the-arm on the right arm on the first two sensors (14 days each, as instructed.) However, on the application of the third sensor, it worked fine for two days. On day three, it was working fine--until it didn't. I'm back on the left arm, but the FreeStyle Libre 2 app scan says "scan complete," but then there is a window that says, "Scan Error Your scan was unsuccessful. Tap the scan button again. OK". Well, that's an eternal loop. It doesn't give me a reading. So, I tried my wife's iPhone, and it got a good reading. That makes me believe that it is the phone--or something in the program--not the sensor at fault.

My sensor sent a alarm to my I phone stating my reading was 68 and my
Doctor set the range between 70 and 180
I immediately took a finger stick reading which read 116 less than 8 minutes later .
This happened over 4 times in a 16 hour period and only on the fourth did I take a finger stick blood test .
The first and second time I took a few ounces of orange regular soda and the second time I took several ounces of orange juice . The third time was about 4 hours after the second and I drank 24 ounces of bottled water .
It seemed that the variable was more than 5 to 10 % differential.
Is this normal .
I also just replaced the sensor on Thursday early evening and the last occurrence I’m referring to was at 12:18 AM and the blood glucose finger
stick was taken at 12:26 AM
Any recommendations?

TERRIBLE quality control on Freestyle Libre2 sensors. On nearly half of them, I get error messages that sensor is not working or repeated messages to try again in 60 minutes. I obviously know how to apply the sensor because half work perfectly for the full 14 days with readings on my Android app that are close to my finger-prick readings when I check. Abbott's phone number yields replacements sent without quibble but it is frustrating and time-consuming to be calling them regularly.

I am a new user. In my first order I received 6 boxes of sensors, enough for three months. Two of those boxes were defective. In the first the IDs did not match between the sensor and the applicator and the instructions said not to use in this case. In the second the applicator did not have a needle, so useless. I complained about the first situation to the online hotline. It was a difficult experience because the hotline person spoke very accented English and was hard to understand. But they did send me a replacement. I opened the replacement today, and lo and behold it also did not have a needle. Something is very wrong with Abbott's quality control!! My second shipment is supposed to come any day now, so I am using finger sticks to monitor my blood sugar control. I will give this product one more try as I found is easy to use and helpful in control--didn't find so much discrepancy in readings as others reported. But I'm not optimistic--a 33% defective rate in a healthcare product is just wrong.

Not one to complain, but as of last three months may have used 2 out Of six sensors without problems. Didn’t know that I could return for replacement. Thought that it was my phone so purchased reader, still had same problems. Now instead of on and off signal issues, and wait 10 minute messages I have gone through (2) more sensors and told to replace again. I am loosing faith in Libre Sensor ability to work period anymore. Wasted too much money at this point not to at least trying to find answers. Guess I need to purchase strips for meter again, too good to be true “usually is”.

I have an iPhone SE. Have had no problem reading the sensor till last week. When I tried to scan the sensor the response was:
Scan Error.
Your scan was unsuccessful. Tap the scan button and scan again.
I would scan again and it would work. but 4 days till the end of the sensor, I could not get a reading. Applied a new sensor, Scan Error again, no reading. Called your help desk, no help to correct the problems. But will receive new sensors.
I need help to "reconnect" sensor to my iPhone!!!!!!

The libre link up is not sending info to the phone of the parents even though the have been granted access. As a parent I am not receiving any readings now at all. The last few weeks the reading were slow to alert on my a 15min delay at least from time of scanning with my childs phone. Now nothing is coming through and alarms are not going off on either of the parental phones linked to our sons app via libre link up. His alarms are still working.

Had a crazy high reading. 15 minutes later i get a can’t read message and to wait 10 minutes. 4 cycles of waiting and it doesn’t look promising.mi have to pay cash and can’t just toss this sensor out and apply a new, million dollar one! I’ll try to call them in the morning. Meanwhile i have no strips to do a poke! FRUSTRATING.

I’ve had problems with my app and my sensors. First thing I had my sensor on and it was working fine then I tried checking it again and it said I needed to replace my sensor even though I still had 7 days left. So then I changed my sensor and it worked fine but today I try to click on the button on the app and it will not let me scan my sensor so I have to go check my sugar by finger stick. This is why I got the libre to prevent me from having to do constant finger sticks but now that it won’t even let me scan my sensor it’s a real inconvenience. Please help

Hi, I called this morning bc my reader has been glitching, after I choose an option or before, the screen goes blank. He insisted it’s my new sensor but it’s clearly the reader. Now I can’t get it to stay on long enough to get a reading. On 5/29 I was sent a new sensor due to me being prompted to start a new sensor when it was only 4 days old, that’s never happened before and it’s when my reader started acting up, I’m sorry I was unable to send the used one back bc my mom thought it was trash. I don’t even know if I was being sent a new sensor for the exchange from today. Idk what to do , please help me. Thank you

This is junk! Had my 1st reader and 2 sensors. The 1st Sensor worked for 4 days and just stop. The Reader could no longer read the sensors and was to replace. Have 2nd sensor on and again a few days later the reader could not read the sensor. Again the reader was "need to replace sensor". Called FreeStlye Libra2. No one there has English as their main language, grrrrrr. Get in the mail a new reader and 1 sensor. WTF. was told I was getting 2 sensors. Cleaned the arm up and put the new Sensor on and the reader is working. 16 hours later. The reader cannot read the sensor, again "please replace sensor". I do not want The Free Stlye Libra2 and will return it. If you are lucky and your stuff works, good for you. If you are thinking about getting this. Do NOT waste your time with it. It is JUNK! I called back the 2nd time to let them know the reader failed to read the sensor. The Lady on the phone kept saying the sensor fallen off. The sensor fallen off. She stopped after i asked her what the [email protected]#$% is her problem. NOPE the sensor still on arm and READER will NOT read it. Then I asked me to replace with new sensor. Then I ripped the now not working sensor off my arm. Stay away from this, it is junk until they can fix it.

Hello, just received my libre 2 meter and sensors from CC's medical. Been through 4 sensors in less than 24 hours. Contacted Abbott through the information on the back of the meter because of the false readings/inability to read my sugar. Will be doing finger monitoring and following up with primary care.

iPhone NOT picking up sensor. It doesn't give sound and vibration that is has read the sensor. There have been several IOS updates with no problems, but this shows that Abbott isn't concerned with Apple making OS changes. Have you noticed how many updates were made the Libre 2 app? Not concerned . . . . . .

Today I have started two different sensors and got the same message, that the sensor is not working to start a new one. What is happening and how can I get a replacement for the two sensors that are not working. This things are expensive. I only have one left and do not want to use it until I know what is happening here. Thanks, Gregory Llinas in Alexandria Virginia.

It started 2 days ago, alarm went off that sugar was at 58 and dropping around midnight. It kept going off, checked my blood sugar with my ultratouch and it was at 88. Woke up the next morning and it wouldnt send signal or scores to phone app. Worked only a couple of times, as i checked my blood continuously though out the day. So I am writing to you to see what can be done, It worked fine all week, until this started as I said 2 days ago. Help !!!

My Libre 2 sensor was working fine for a few days. I started getting low glucose alarms so I took food and sugar. The next day it did it again and I didn’t believe it was accurate because I had eaten a lot. I did a finger stick and it showed my glucose was 189 where the sensor said it was 69 and going down. My readings for the past week were low so I wasn’t injecting very much insulin. In turn my glucose has properly been high and I should have been injecting more insulin.
I am disappointed with these units. I’ve already had to replace 4 sensors in the last few months. I like not having to stick myself multiple times a day but it is getting very frustrating when they don’t work.
Thanks for your response.
