FreeStyle Libre 2 Sensor

I had resisted buying these because of the price but I decided to use the $15 trial. It was easy to attach to my upper arm & shows no sign of coming unstuck. It seems to be very accurate (against a finger prick). However the app is incredible unreliable, I now make sure it's within 3 metres even at night & Bluetooth is always on but it often loses… Read more

connection. Also when I place the back of the (Samsung) phone it mostly does nothing or gives an error. On rare occasions it works. A long term user advised me to try "the other brand". I have though ordered a different brand that works out at half the cost.

These sensors are terrible inaccurate, expensive and fail at random. Since Christmas I have had four that have failed. I contacted Abbott to replace them as in Japan these are AUD$800 for two if they’re not covered by insurance. Because I didn’t keep the box, they refused to accept the screenshots of the errors and asked me three separate times… Read more

for serial numbers. The app only stores the last three so if you have more than three failures, or they don’t upload into the app, they refuse to help you. I’m beyond annoyed. The readings are also always ten to fifteen points under a manual glucose monitor so don’t waste your time.

This product is bad. It's sensor was terrible and showed lower results, resulting everyone believing it was low blood sugar, resulting taking lot of sugar drinks to bring level up. After panicking and visiting GP, when tested in lab, the reading was much higher. When I spoke to technical support, they refused to send me replacement or refund… Read more

saying that they need doctor's report. With so much suffered already including multiple Doctor visits and lab test, I am not in a position to go to doctor again. They refused to help. Bad experience. Going with Dexcom, which has great reviews. This is terrible company and terrible product. Honestly avoid this.

This product is rubbish and as a medical device should be banned. The sensor drops out frequently and is very difficult to reconnect. The peak readings are up to 2 mmol/L below the values returned by a pin prick after meals. Overnight multiple hypoglycaemic readings when pin pricks during the night always show above 5 mmol/L. Show details

Rv about customer service - initially impresssed had one sensor not work called and replacement sent out, decided to try subscription not worth teh 20% off if you dont recieve it, customer service even though sensor tracking last updates 8 days… Read more

Dear Tech Team, I am writing to request an essential feature for the Freestyle Libre 2 Plus follower app: displaying the remaining time for the sensor's usability. As a subscriber for my 72-year-old mother, who depends on the Libre 2 Plus to manage her fluctuating blood sugar levels, I deeply value your product’s reliability. Despite other… Read more

options claiming superior accuracy, we remain loyal to Libre 2 Plus and have used it for some time. However, as I do not live with my mother, managing sensor replacements is challenging. The follower app currently does not indicate when the sensor is nearing expiration. My mother, who has poor vision, memory issues, and limited tech proficiency, cannot track this information herself.

This creates significant difficulties, as I work shifts and often cannot replace the sensor immediately when it expires. This results in gaps in monitoring, which is concerning given the risk of undetected low/high blood sugar levels. Adding a feature to display the sensor’s remaining time on the follower app would allow me to plan replacements proactively, ensuring continuous monitoring before my shifts begin.

Thank you for considering this improvement to support users like my mother and caregivers like me.

Sincerely,

I have been using the Libre 2 sensor for the past 10 weeks, but my recent experience has been extremely frustrating. Yesterday, I applied a new sensor on my left arm at 9 PM, but by midnight, it failed and kept asking me to rescan. I tried three times, but it didn’t work. The worst part? It stopped working when my glucose reading was at 2.9… Read more

(dangerously low), putting me at serious risk. After an hour, it started working again, but then failed completely and now asks for replacement. This is unacceptable for a medical device that’s supposed to help manage diabetes. What’s even more disappointing is customer service’s response. When I called for a replacement, they refused, claiming my Samsung Galaxy A73 (5G) is not compatible. Strangely, their list includes older 3G Samsung models but not newer 5G phones. When I initially subscribed, I called customer care multiple times, and they never once asked about my phone compatibility. Now, after spending money and relying on the product, they tell me my phone isn’t supported? How can a billion-dollar company like Abbott not ensure compatibility with modern smartphones? If they market this product through diabetes educators and endocrinologists, they should clearly inform users about compatibility issues beforehand—not leave them stranded after purchase. Additionally, my diabetes educator trained me three times on proper sensor application and even recommended a transparent bandage for extra support. Yet, the sensor failed within 15 hours. Now, Abbott expects me to carry their separate scanner instead of using my phone—this is not practical in 2024! Extremely disappointed with the unreliable performance, poor customer support, and lack of transparency. Abbott needs to improve sensor durability, compatibility, and honesty with users. Right now, I cannot trust this device with my health. ★☆☆☆☆ (1/5) – Needs major improvements!

Not perfect but worthwhile – I have been using these constantly for over a year now for my type 2 diabetes. They are much better than finger pricks and have made it much easier to control my bsl. Some general feedback: Mine only come off early when I catch them on a door frame etc maybe once every 3 months on average. So not often but still it’s $100 gone each time. I… Read more

regularly get sensors that stop working after only a few days. Most of the time I ring Abbott and they send me out a new one for free. Sometimes I couldn’t be bothered calling because they ask for a lot of information and ask you to send them back the old one which is time consuming. But every time I do they send a free replacement.

The sensors are not 100% accurate. I have checked mine against two different finger prick tests many times and the sensor is always a bit lower than the finger prick test. Sometimes my sensor says 6.0 and the finger prick tests are 7.0 sometimes the difference isn’t as big but it’s always a bit lower. The difference is much more pronounced in some sensors.

When I’m inactive (laying in bed) the sensor reads lower than when I’m up and moving about. I think maybe because the fluid in my arm it’s reading from is not circulating around as much? (That’s just my uneducated guess as to why it happens but either way it definitely happens, it’s been that way consistently for the whole time I’ve used them which is over 12 months). My reading will often drop to 4.0 or 4.5 when I’m laying down but will increase to 6.5 when I’ve been standing up for a while.

If I lay on the side where the sensor is it drops very low and will set off the alarm after a while I.e. it drops below 3.3 even though it’s actually 5.5 or 5.0. Bit of a pain when it’s in the middle of the night and wakes you up. If I lay directly on the sensor it will drop extremely low (below 2.0 where it stops giving you a number and just says “LOW”) even when it’s actually 4.5 according to a finger prick.

Despite these faults I still subscribe and get two,new ones every month. They play a big part of me successfully keeping an A1C level of 5.5. Before these it was up over 13 and worse. Just have to keep in mind that it’s not completely accurate and when you get unusual readings, verify them before acting on it because it’s probably wrong.

It’s very expensive for type 2 because they are not subsidised like they are for type 1. Obviously that’s an issue for the federal government not Abbott but I wish the government would include type 2 in the funding. Maybe at least when a Dr indicates close monitoring is reasonably necessary.

Charged $111 for a $15 trial. I realised immediately and requested to stop order and get a refund but no response from Abott. Update: Abbott Diabetes have refused to give a refund. Avoid this company. They overcharge and refuse to compensate. My next step will be to report this behavior to my state Department of Fair Trading.

Libre 2 SUCKS when used with an android phone. App constantly sounds irritating alarms - it can't be stopped! The app also constantly displays a message "Alarms Unavailable" while it is repeatedly sounding alarms. Spent an hour with support that never really understood the problem. Her only remedy was to try another sensor, which of course did… Read more

nothing. She was to send me a form to request a replacement, but I never received the email, so I'm screwed out of a sensor. Prepare to spend HOURS working out Abbot's application bugs.

Absolutely pathetic, I used to use the model before and had managed to get most of the sensors close to the length they would run for. I jumped in the pool today and 1 day in the new model came off. This is after doing everything they say to do. This is not the first time using this sensor and I think the longest I got one to last for was about 9… Read more

days. With the older sensor I used to get half way through before I would put a patch over as the patches don’t last for 2 weeks. These now sensors are rubbish!!! I will look into another brand now. Useless crooks!

Had used these sensors a couple of times to track my blood glucose levels as pre-diabetic - was never particularly accurate when compared to a finger prick test but enough for me to monitor trends and make some food and exercise changes. Last one I ordered was faulty and died within a day of application with a error in the app. Abbott refused to… Read more

replace without a letter from my doctor saying it was suitable for non-diabetics, which would probably cost me nearly as much as a replacement. Reported to Customer Protection but they couldn't help. Won't be buying again and would suggest you look elsewhere for a company with better support options.

What a joke. poor support order a free style patch one month ago in WA . pass the buck with DHL Australia Post . waist of my time in post office cockburn for over one hour. unable to find LIT . wake up have more respect for seniors, N02951663

I took advantage of the $15 trial and then became a subscribed member. The trial FreeStyle Libre 2 Sensor lasted 10 of the 15 days. Once subscribed, no sensor has got to 10 days, (it is meant to last 15) and one only lasted three days. Social media even now markets third party sensor protection items, seemingly to fix the problem in built in the… Read more

Freestyle Libre 2 Sensor. I have turned my subscription to an indefinite hold and now have to start again with a competing product.

Three sensors have failed (2 in the last four weeks) and the only fix is to send out a replacement (band aid solution) which does not address the quality control issues. I spoke to one of their (Abbott Pty Ltd) customer service officers who would not allow me to lodge a complaint over the phone nor provide me with a complaints email address but… Read more

instead advised me to refer to your webpage but there is no email address on your webpage, hence this message. I now also now want to lodge a further complaint for the time wasting and incorrect information received. I cannot recommend Libre products nor the support after my current experience.

Since using the CGM I've had no issues except my phone wasn't completely compatible with the monitor but I would genuinely appreciate it if y'all remember alcohol wipes to clean the area before placement it's only the second time this has happene, I had to use baby wipes instead of the cleansing wipes the box usually supply's.

I am Type 2 and have been using Libre sensor for many years. 1 out of 5 or 6 of the sensors always ends up having errors. Wakes me up middle of the night saying I'm having a low (2.9) but when I do the finger prick, my blood sugar reading is 7.9. When I call the customer service, they always replace it but it is such a HUGE waste of time… Read more

answering all the questions. I have given them feedback for the past 3 years abotut sensor errors but nothing has been improved. VERY DISAPPOINTED. And it is very dangerous for diabetics who are not aware of these sensors having errors. They would think they are having a hypo and end up overloading on sugar and damaging their organs.

The first one I tried had Inaccurate readings, told me I was 2.4 and I was 8.1 on finger prick, I got another to see if it was just that once off. Still not accurate by 2-3 sometimes more, also after 4 days my top got caught on it and pulled it out. Not worth the $ also not sure how FDA have approved this!?!?!? Show details

Died after 4 days. No customer service details in instruction or box..trolled deeply to find a tel number for help on website for a replacement or refund. Used "callback for help" options and after 1 hour..still waiting for a call. Not happy Show details

I have been using the sensors for over 1 year & I love not having to do finger pricks but reliability of the sensor is a definite issue. The sensor stops working if I do any manual labour. It seems vibration or sweating causes the sensor to malfunction. This is extremely frustrating as these are the times that I need constant monitoring.

Potentially DANGEROUS – I have been using the FreeStyle Libre 2 CGM since October 2023 and therefore familiar with its use and, generally speaking, I have found the sensors to be a useful tool in monitoring and managing one's diabetes and ongoing treatment. That said, however, the sensors are not perfect and when they are not reading one's glucose level accurately, they… Read more

are not merely not to be relied upon but potentially detremental to health and safety. Below I summarise a recent experience. Note that I intend to continue to use the sensors, but their use must be made in conjunction with ongoing blood glucose testing by tradition methods. One cannot just "set and forget". Sensor started on Tuesday 28/01 - initially appeared accurate and did not do Blood Glucose test. Over time, Sensor appeared to be reading significantly low, so started taking Blood Glucuse test readings on 31/01. 9:21am - BGL 6.4, Sensor 4.5 (1.9 variance), arrow steady. 10 minutes - Sensor 4.1 (2.3 variance), arrow steady. 11:03am - BGL 12.4, Sensor 9.2 (3.2 variance), arrow steady. 5 minutes - Sensor 8.7 (3.7 variance, arrow steady. 11:22am - BGL 9.9, Sensor 7.1 (2.8 variance), arrow angle down. 5 minutes - Sensor 5.7 (4.2 variance, arrow straight down. 11:53am - BGL 7.9, Sensor 6.1 (1.8 variance), arrow steady. 5 minutes - Sensor 5.3 (2.6 variance), arrow steady. Called ABBOTT Customer service who responded that while they would replace Sensor, according to their calculator the performance WAS WITHIN ACCEPTABLE RANGE! The degree of variance from Blood Glucose test readings renders the Sensor not just unreliable, but potentially dangerous to the user and the public if, for example, one were to rely upon the Sensor reading to determine if it is safe to operate a motor vehicle or to guage the amount of insulin the user requires. When the Sensors work within advertised variance (0.5 or so), or when the variance is large but relatively consistent, the Senors are a useful tool. But when the variance exceeds 4.0 in one reading and 2.6 the next, the Sensor reading is worse than useless, it is dangerous. Most the time the Sensors are relatively useful, but Abbott needs to acknowledge their technology is not medically reliable, which could lead to harm to the user and the public.

Appalling - no service – only gave one star as couldnt review without one ! Appalling service been using these for years and last few months off insulin .On request to replace broken sensor (on opening) they finally ask if Im on insulin so I told them honestly and then they started the whole need a Dr letter to confirm you can use it etc as others have said . WOW really… Read more

the product is faulty regardless of my status so needs replacing ! They haven't enquired if Im on insulin or not over the past 5 years (approx) as they have taken my $$ See photos for details please disgusting lack of service

Faulty sensor requires doctor letter before consider replacement as I don't take insulin – Emailed Abbott saying sensor had failed and with brief details, then got request for more information and spent ages answering even more questions to get an email back stating that as I don't take insulin I will require a doctors letter. So annoyed, firstly as they knew I dont take insulin by my first contact and still they asked for me to spend… Read more

considerable time answering more indepth questions before replying with the doctor letter request. Feeling very angry at the moment.

What a waste of money!! – I would not suggest purchasing this product. I purchased it, followed the video instructions for application. The product worked at first, syncing to my phone and providing updated but then fell off my arm in less than 3 hours!! This product is supppost to stay on your arm for 14 days!! I contacted the customer service to request a replacement and was told I had to get my doctor to write a reference!!! What a waste of money!! Show details

Forget your Australian Consumer Rights, these guys don't care! – After several deliveries and successful operation of the sensors (was signed up for the subscription - regular deliveries), we hit a problem. The sensor came up with an error, it wasn't during obtaining a reading, the sensor was actually faulty and said as much via the Bluetooth error message that came up. However, Abbott Diabetes Care hid… Read more

behind their warranty stating that as a doctors recommendation to use the device was not provided, the warranty was void. Even after pointing out to them the Consumer protection laws, they maintained their position. But here is the kicker... Australia's finest consumer watchdog, the Office of Fair Trading, again proved absent at the wheel! A total waste of time and effort, but that is another story. We have consumer protections, but no efficient way to use them without the need to go through QCAT, waste 20+ months waiting for a decision, and lodgement of the claim costs more than the device.
