Dexcom gave me a call after I started using the One Plus. I’ve not had a problem with the Dexcom, but did suggest that they include an alcohol wipe with every sensor. the Libre adhesive was very poor, I found it necessary to shave my arm (no, I’m not an Orangutan) and clean the area with surgical spirit. I also used a Skin Grip over patch. I have noticed that the Dexcom adhesive is very strong and the over patch included in the box works well.If a CGM has a manufacturing issue where not enough adhesive is consistently being applied to make it stick to your arm then it clearly isn't fit for purpose. I've worked in medical supplies for 30+ years and have also been a customer of Abbott for many of those. I made my thoughts very clear to the MHRA and I've had Abbott call me acknowledging they are aware of the issue.
I have kept the two worst examples for the MHRA to inspect. You know there is a problem when no Mark has been left on your arm after the thing falls off and you can barely notice any adhesive on the CGM when you touch it and it's pure white in appearance rather than the normal greying of the adhesive after use Both of these examples were replacements that came directly from Abbott as I've had 7 fail due to adhesion, 1 fail due incorrect readings and only one which lasted the duration. So 9 in total over a period of about 6 weeks.
Interestingly my diabetes nurse has been testing the Libre 2+ and hers never managed to last more than 7 days while the Dexcom one+ consistently lasts the 10 days. This is also my observation.
I have also used the Libre 2 previously for several years and while I did occasionally have replacements I've never had them fail so consistently as the Libre 2+..
You should also not need to purchase anything such as a sleeve or plaster to enable you to use these items. These companies are being paid a small fortune by the NHS and if additional items are needed they should be in the box!.

I made my thoughts very clear to the MHRA and I've had Abbott call me acknowledging they are aware of the issue.I've had a very low failure rate with the Libre 2 and more recently the Libre 2+. I have had one fail (after 2 days) and one come off in my sleep, and that was before I started wearing a stretchy 'armband' over it . The armband is breathable and comfortable and protects the sensor unlike other solutions involving extra patches, adhesives or 'sticky' wipes. For the two problems I had, Abbott were very quick to replace them for free.
I concede that there are a number of people for whom they won't work for whatever reason, and I've listed a number of possible reasons below. It may be a bit strong to say that as a product it's not fit for purpose when there isn't clinical evidence to support this assertion, all we have is anecdotal reports on a handful of user forums. If it doesn't work for you, perhaps work with Abbott to try and sort it or get your GP to prescribe a different brand? Good Luck!
Hope some of this may help those facing challenges with CGM sensors.
I'm curious as I've had so many issues, do you use anything to keep the sensor in place?.Had a few issues with Libra plus2 but overall they seem to be fine, some times it says glucose levels paused? and yes Abbott has always replaced any faulty sensors I've reported to them.

Yeah they don’t last the full days. I act to replace mine with 5 days left. Dexcom one+ seems to be better. Starts up quicker, comfy, and doesn’t hurt when you even put it on.

I’ve been using them for three years and I think only 3 have fallen off in that timeY

Have a word with your doctor to see if he can prescribe an extra sensor on your prescription, Fortunately, my doctor doesn’t stick rigidly to prescription repeat dates so I always try to put in a repeat prior to starting my last sensor. If you’re living in a remote area he should be able to justify it. My last doctor was happy to issue prescriptions for two months, yes it was against the rules, but he said he could justify it on the basis of the delays in obtaining some items. I tend to keep additional insulin to hand, as I’ve had awful delays with the local pharmacy being able to obtain it.New sensor yesterday DoA. That's a first for me. Zero readings logged whatsoever. Woke up alarm from it at 4.19am urgh.
Abbot's customer service usually good sending out replacements.. shame courier company they choose isn't as good nor helpful wouldnt be difficult for them imo to give a tracking reference... So don't need wait in umpteen days. That's one disadvantage of living in the isles.. courier services suck bad, never is next day delivery unless royalmail used
Would appear that we are seeing messages that we never saw with the previous sensor and the firmware in the sensor has been updated to the point where it is finding fault where the old sensor never had this level of checking then they were not perfect but at least carried on working.New sensor yesterday DoA.

complains frequently if getting prescriptions 'early' to the point that the senna i use (prescribed 28 at a time... take 1 or 2 daily as required). sometimes im needing 2 sometimes 1 othertimes none as the pain meds give me constipation resulting in rectal bleeding.. i needed after 16 days more senna and spend several days arguing til received. really depends on which dr is actually signing the prescription. my own dr doesnt have issue when see in person if need something a little early. the other dr at the surgery always is issue alongside when the pharmacist there signs repeats doesnt tend to do 'early' repeats in her view is a months supply.Have a word with your doctor to see if he can prescribe an extra sensor on your prescription, Fortunately, my doctor doesn’t stick rigidly to prescription repeat dates so I always try to put in a repeat prior to starting my last sensor.

I'm actually overall pleased with the libre2 plus
I took up the free trial for Dexcom One+ and have found it works really well, I’m on sensor number 5. A very small gripe from me is I’m lazy carrying a phone around the house so have now turned the lost signal alert off. If you give the Dexcom a try, and decide not to change, at least you’ll have a spare freestyle Libre sensor stored away without your doctor ever knowing!https://www.dexcom.com/en-GB/dexcom-one-plus-sample @grantg you could try this. Free trial and see if that is better for you. I had it in for days now. It’s only 0.2 at most out and starts up really quickly and reliable in first 24 hours unlike libre
I always have spares luckily. One thing good about Abbott at least they replace all bad sensors for me and have been very good about it but it’s a pain having to fill out the same stuff all over again. Dexcom have a limit with replacements unfortunatelyI took up the free trial for Dexcom One+ and have found it works really well, I’m on sensor number 5.

I like it so far and I love how you can calibrate it. Mine was higher than blood and you just enter the blood % on the settings and it fixes itI took up the free trial for Dexcom One+ and have found it works really well, I’m on sensor number 5.

Weirdly there are 3rd party apps for the Libre that can send to smart watches..I like it so far and I love how you can calibrate it. Mine was higher than blood and you just enter the blood % on the settings and it fixes it
Calibration is great when works. Best calibrate when graph shows flat as possible. no point calibrating eg blood sugar on downwards trend it still uses interestrial fluids same if upwards trend.I like it so far and I love how you can calibrate it.

Any ideas on what the Dexcom replacement limits are? I’ve not had a problem, and haven’t needed a replacement, but I do feel that we have a certain amount of responsibility to look after these sensors. I restore classic cars in my spare time and take reasonable steps to protect the sensors from knocks and abrasions. Without taking care I could probably destroy a sensor in a couple of hours!I always have spares luckily.

Totally agree on this.Calibration is great when works. Best calibrate when graph shows flat as possible. no point calibrating eg blood sugar on downwards trend it still uses interestrial fluids same if upwards trend.
There are 3rd party apps around which can give libre sensor same calibration control

I never used any 3rd party apps but my diabetes nurse told me you could get readings on the watch by that way.Weirdly there are 3rd party apps for the Libre that can send to smart watches..
But I’ve never had the need to use the calibration feature. normally & approximately within 0.6Mmol for me with a meter. Give or take any interstitial fluid lag?
I can live with that..
dexcom said:Dexcom will replace all sensors that we confirm as failures during the intended lifetime of the sensors through investigation.
https://www.dexcom.com/en-GB/sensor-replacement-policy Limit max 2 every 12 months period for the dexcom one+
it further makes the reference to 2 dexcom replacements. that is for Non Defective monitor issues.dexcom said:In the event a user requests a replacement for a non-defective sensor (sensor removed for a procedure, user application errors, etc.), the user will be provided with educational materials in the hopes of preventing future issues. In addition, as a gesture of goodwill, Dexcom will provide replacements if needed to ensure continued sensor supply, in a limited quantity each year.
