Libre 3 plus has failed twice since I started using them in December of 2025. The company sends you a new one when you call to complain but it takes 5 days to get it. For 5 days I am with out a sensor. This has happened to me 2 times. They should send me 2 when they replace it so when it happens again I’ll be prepared. Notice that I said when and not if it happens again ! Losing confidence in this system. If it keeps happening then I’ll switch to their competitor. Dexcon 7

I used Freestyle Libre 3 Plus.

Recently I updated to a new sensor fails which fails 90% of the times with the error "Sensor Error"; Reached out to Libre3 Plus customer care insists me to buy "Libre3 Freestyle reader" to use their sensors. Other Option was to use a iPhone that has outdated iOS version.

I have filed a complaint to customer care to update the Libre 3 Plus App for the latest iOS version. There are many who relies on Abott for glucose monitoring but Abott is Out of date with the technology in 2026!.

Had 2 sensors that failed and was advised by my GP to contact Abbott directly. I did not expect any joy but was completely wrong. Abbott replaced my 2 sensors and they were with me in a little over 24 hours. The response and service was truly superb although the customer service guy was a little difficult to understand because of his (Dutch ?) accent.
Would have been 5 stars but for the sensors initially failing.
Well done Abbott, great job

I've been using the FreeStyle Libre Plus for a while now, and my experience has been mixed.
On the positive side, I like how easy it is to apply and scan. It's convenient not having to do constant finger pricks, and it gives a general idea of where my blood sugar is trending throughout the day.
However, accuracy has been a big issue for me.
There have been multiple times where the readings didn't match how I actually felt or what my fingerstick showed. It can show highs or lows that aren't really happening, which makes it hard to fully trust-especially when making decisions about my health.
I also noticed that the readings can fluctuate a lot, even when I haven't eaten anything or only had water.
That can be confusing and frustrating.
Overall, it's a helpful tool for trends, but I wouldn't rely on it alone for exact numbers. I still find myself double-checking with a fingerstick more often than I expected. Overall free style libre plus sucks it says my blood sugar was 183 checked by finger stick it was 91

If there was a zero I would put that... I lost two of my libre two sensors and when I explained to the person the first time I was put on hold for 47 minutes and hung up on. Then I called back spoke to somebody else. They instantly hung up on me. When I told them what my issue was. I had two of my sensors that fell off. I have the omnipod 5 and therefore need the sensors I explained to them that I'm on blood thinners and when I tried to put one on it caused me to bleed really badly and got all over the sensor. The box everything my bed and so so I told him I did not keep the box. I don't keep things like that. That's gross. So I also explained I threw out the box of the other one cuz I had already had it on one week and somewhere out in public because the adhesive is so cruddy it fell off somewhere and because I didn't have the box they wouldn't replace the two sensors. They're they're representatives are very rude. They are not helpful at all. Abbott is a very greedy company where they can't just send two sensors out to somebody who's on a diabetic pump who already has kidney damage. I would not recommend these people to anybody and I plan on changing to a different company with a completely different sensor. I give them zero Stars and -10 for the personalities of their representatives

Lately, the quality of Freestyle Libre is below any acceptable standard. I've been wasting money on the sensors that work internmitenly, disconnect all the time, refuse to be read, but I learned to live with it as there's no other way, other providers are either very expensive or not covered by my insurance.
But this time is different - THE SENSOR VIRTUALLY STOPPED WORKING AFTER 4 DAYS AND ABBOTT IS REFUSING TO REPLACE IT!

Besides sensor falling off often, the sensor is not accurate. Ive compared it to fingering sticking and it could be off as much as 50 points. Continuously low glucose going off especially at night maybe up to 3 or 4 times. If you use this product you could be taking your in their hands. Ive gone back to the finger stick. And it failed to record these events. About 7.

Abbott Freestyle displays 4.2 when it's actually 5.7 :-((

That's 27% off, and Abbott claims it's not necessary to calibrate the sensor.
The nightly alarms should ring the ceo of Abbott, they would remedy immediately :p

I have been using libre sensors for years the two and three models were okay but now this new libre 3 plus sensor has about a 95% fail rate always low and the replacement sensors that they send you fail at the same rate are they ever going to fix this or are we going to have to change to a different brand

These sensors cost me $100 each, only last two weeks and FAIL 50% OF THE TIME. I have to fight with the pharmacy to get a replacement because Abbott wants the customer to send the failed sensor back to them directly. THIS IS THE WORST PRODUCT I HAVE EVER USED. I have flushed at least $600 down the toilet this year because of failed sensors.

I have never had a problem with customer service got a new sensor freestyle libre 3 plus twice now because one fell off every month since October. It’s now staying on thankfully.

Been using freestyle libre, two and three pluses. In the last year and a half I’ve experienced well over an 80% failure rate the 3+ I’ve been using since October. I’ve only had two sensors that I’ve worked adequately enough to be usable. The remainder all die or are aired out within 2 to 3 days of application. They never read correctly always read low off by up to four points truly not worth the money that they’re billing insurance companies to pay for it was a great idea, but the technologies is crap. Make your needles thicker or able to withstand the ability to accidentally roll on it while you’re sleeping maybe do a little better R&D development or just declare bankruptcy and fold as a company cause you guys are crap.

Abbott labs will not replace my freestyle libre 3+ reader because they only send you one per year, despite the fact that the reader they sent does not read the test strips. So even though it’s a defective product, they won’t replace it until a year is up and want me to buy a new one; how do I know that one works? No wonder Abbott labs gets such a lousy score from customers. They don’t care about customers at all just about making money.

Convenient and painless to use. Obviously complicated to manufacture, hence the price. The app is brilliant, giving loads of data and analysis. Great when readings are accurate but garbage in, garbage out when not. Sometimes the sensor readings are wildly inaccurate, checked against finger prick devices . Extreme caution needed if insulin user. Checking against finger pricking device is necessary to avoid injecting wrong doses of insulin which renders the Abbott sensor device superfluous and not required. I've found Abbott's telephone customer help service to be very good with a replacement for a faulty sensor sent promptly, free of charge. However, this system needs improvement in its accuracy to be useful and safe for insulin users. A great idea but not yet practical. Sensors sometimes prone to fall off or sometimes cease working prematurely. Obviously manufactured and improved by highly skilled people, I wonder if it can be put right, given its fairly long time on the market; they must have tried long and hard. Perhaps an impossible task.

I experienced a payment processing issue — my payment went through, but the order was not fulfilled. I contacted Abbott via their official support email (Free_Style_Libre_Service_nl ) with all relevant details.

The problem: Instead of resolving the issue via email, they instructed me to call their call center. No alternative was offered — no callback form, no WhatsApp, no secure online portal.

Why this is problematic:

Phone calls during business hours are difficult for working people

No written record of the conversation or resolution

Language barriers make it hard to communicate technical/financial details accurately

I cannot attach screenshots or documents over the phone

My feedback to Abbott:
It's 2026. A medical device company handling sensitive customer data and payments should offer modern, asynchronous communication channels. Email support should actually support, not just redirect to phones. Consider implementing:

Secure online forms for payment/order issues

WhatsApp Business for verified customer communication

Callback scheduling (customer chooses the time)

Proper email resolution workflow

Disappointed that a company of this size cannot resolve a simple payment issue without forcing customers to call.

My sensor did not work while I was traveling. I had a five hour flight and had no idea if I needed insulin or what I could eat. Because my destination was out of province I had to pay the 100.00 for a new sensor. THEY WILL NOT REIMBURSE ME. SUCH POOR CUSTOMER SERVICE. More and more sensors are defective

About one sensor in three is defective, and they are very costly. I have written to Abbott in Montreal and received no reply. Finally, after several emails from me, they wrote back and said, ''Buy another product.''
They are costing me and the Quebec government a fortune, and they are not only incompetent and dishonest, but arrogant to boot. Is all British technology like this? I have heard that it is. Too bad.

Abbott will not replace my faulty reader because part of the serial number has worn off. I called a week ago and they were aware of this and asked that the reader be returned to them when they sent the packaging. I call a week later and my replacement is on hold because they don't have the complete serial number!

The guy is a crook, he starts out stating he is on baby aspirin, and working 30 different projects. Avoid this crook at all costs. A train wreck

I am a diabetic type II, recently, I changed to a new sensor (Libre3) only to find that my cell phone app no longer works. I have attempted to call Abbott Laboratories but I spend several hours a day for the past 8 days but cannot reach them. I have resorted to using test strips as I am no longer have any way else to check my blood sugar. This is the holiday time and there appears to be no one answering phone lines. Currently, I have been on hold for 30 minutes with no end in sight. Last week, I was able to reach only non-English speakers who could not understand what I was talking about. They ended up simply by hanging-up.
