Freestyle Libre 3 Continuous Glucose Monitoring System

Hard to review. It is what it is. It's quite expensive, but probably the best option if you want to track glucose levels. It arrived on time and packaging was ok, but that should be standard!

For a product so expensive the performance is AWFUL.It’s fairly easy to set up though terrifying when you first get it out the pack, I was nervous to put this in but honestly you can’t feel a thing which is super surprising because I’m normally a big baby when it comes to things like this. The idea with the app and everything is great but unfortunately the performance doesn’t hold up.This product is supposed to last you 14 days mine stopped working after 2, if you look online there is several people who have the same issue consistently and the company apparently is very good at replacing dodgy sensors but in all honesty I don’t really wanna use the product again after my experience.I set the low glucose alarm to go off when I was below 3.9 mmmol/L and it was beeping at me so many times throughout the day leading to me freaking out, I’d then check with a traditional monitor and it would be completely fine.It would also say low the alarm would go off then I’d check on the app and within a few minutes that low reading would completely disappear and it would show as 4.8 or 5.0 or something within the range which I found odd.If you need to wear a CGM it is obviously important you get accurate results, you don’t with this product so it is not worth the money.I also had weird pains throughout my left arm whilst wearing this that disappeared after I removed it, sure this could be placebo but honestly I wasn’t bothered by its presence at all so I’m not so sure. I had pulsating and aches like I had never experienced it was very strange, it could be possible that I had poked it on a nerve and there is also the possibility of the EMF from the product effecting me in some way as it is over the safe recommendation.

I started using the Freestyle Libre 2 several months ago on medical recommendation to monitor my glucose levels as a Type 2 diabetic. However, a number of the sensors failed to connect or remain connected and several sensors were replaced free-of-charge. I switched to the smaller and dearer Freestyle Libre 3 which is both easier to apply and very reliable. Having a constant readout of my blood sugar has proved educational and much easier to maintain control than the finger prick testers.

The sensor did not work. I applied the sensor as instructed (very simple procedure) and scanned, after 10 minutes the app advised a new sensor was needed. I repeated the rescan several times, always the same error.Contacted the supplier they advised nothing to do with them. Refuse to refund. Advised I have to speak to Abbot- the manufacturer.Customer services at Abbot informed me thsy this version of the product (freestyle Libre 3) ‘is not available to buy in Uk’ (well legally at least) it is only available via prescription in the NHS. This company is therefore selling products illegally. The product appeared to be genuine so presumably imported from abroad or perhaps somehow they came across a broken batch that were not intended for resale. However it is impossible to be certain what it was and it is quite scary to think I’ve injected myself with something and i don’t know where it is from. I will be using the manufacturers official website in future.

I was slightly nervous about buying this, having read some negative reviews here about sensor failures, but I ordered, it arrived, and it worked flawlessly for the full 14 days. So I did not need to check out the after-sales service.I bought some waterproof plasters on Amazon and used one to protect it when showering, so maybe that helped. The sensor was easy to setup and worked fine with my Pixel 8.I don't have, nor am I worried about, diabetes; I am only interested in monitoring my blood sugar levels from a self-care point of view. The app gave me a GMI score of someone who is pre-diabetic, but reading online indicated that this is misleading for someone who has not been officially diagnosed with diabetes.It was fascinating to watch how my blood sugar level reacted to the various foods I consumed over the two weeks.

Not convinced about the quality of these sensors- i have had one before through the Zoe trial and the highs and lows were far more extreme.I did some finger prick tests and they gave me lows that never showed on this sensor - one day i had a glass of wine on an empty stomach and felt jittery. Sensor showed a reading of about 4.5 but the finger prick showed 3.5. The sensor never picked up the low.It also never registered me high in range or out of range.If you are diabetic i would get them from Abbott and pay the extra. If you are wanting to understand your glucose levels to help manage symptoms there may be some value in these ones but be aware of the accuracy issues

Sensor failed to Pierce skin after applying correctly so registered a failed connection after 10mins. unless you like throwing away £79 needlessly do not buy. This technology seems to be very hit & miss it works buy trying to stab a subcutaneous sharp probe in place under the skin! Which seems to be not up to the job and the price for this unperfected gadget is ridiculous

I have tried a number of continuous glucose monitors and the Libre 3 is one of the best on the market. I can check the accuracy using a manual strip tester that is known to be highly accurate (Swiss Countour Plus Blue used as reference). The Libre 3 readings are within 15% of the manual strip tester but tend to lag by about 5 to 10 min. Still very useful to have things monitored and graphed out in real time. You must keep the Libre 3 phone app OPEN or it will disconnect from your phone I learned. Nothing beats the finger prick manual glucose strip monitors for accuracy but this does come close and is useful to view trends. For example, if you eat a few pieces of candy you can see the graph spike up 5 to 10 min later and then comes down 30 min later.
