I am having trouble with these. The last three I have used it has been necessary to ring Abbott and report faults. Not the first time in the years I have used them as having to report faults at least every two months. The last three in a row has got me upset. While Abbott replace the faulty sensors, it is not a simple process. Many minutes on phone and often it is difficult to understand the person dealing with my issue (usually average english).

Has anyone got some advice as whether Libre 2 or Dexcom system is better and how reliable is the Dexcom system.

David, I also had problems with three L2's recently, so I think they had a bad batch.  But my last two sensors since then have been accurate and reliable.

The first bad sensor had a bias, but that was manageable and I didn't seek replacement.  I had two sensors replaced because one was far too inaccurate and the other expired after a couple of days.  

For each, I crossed-checked results with finger-prick tests via a very old Freedom Lite (15+ years ?) and a modern Libre 2 reader.  The two finger-prick devices agreed very well, which I thought was impressive.  I use a timer on my phone to delay the L2 scan to accommodate the delay between finger-prick and interstitial readings.

The two sensors were quickly replaced at my request but, yes, I had to provide my test data and serial numbers of the finger-prick devices etc.  They only wanted three test readings, which I think is insufficient, but that's their problem.   I also needed to upload the error data to Abbott.    Because my Freedom Lite was a far beyond support, they also replaced that , which I didn't request.  I had to return the bad sensors and apparently they're checked in Sydney, but I can't imagine Abbott spending time to check all the devices that are returned on a global basis.

Call centre people in most areas these days are based overseas, but I've never had a problem understanding Abbot's people.  My last person seemed to be well informed and was based in Malaysia.

As a monitor/control device I don't expect them to always agree with finger-prick readings but we should cross-check periodically.  Both finger-prick and interstitial devices are just an estimate of the true BG and I'm very grateful to have them both - much better than the old urine test-tap which I used for many years.  But I'm looking forward to the Libre 3.

It will be interesting to hear about the experience with other brands, because I've only ever used Libre.

Hi !

I have had very good results with the Libre 2. One or two failed but were replace quickly.

The main issue I have is that Abbot does not let the user know why the device failed. This means that if the problem is caused by the user there is no feedback to allow  me to modify what I am doing.

Abbot really needs to modify this process !
