I'm type 1, diagnosed 3 years ago. I've been using Libre for about a year now after being advised at the diabetes clinic. I have brought my HbA1c down to 6.4 at the last reading, this is mainly because I got a good insight into what was happening overnight. I haven't had a night hypo since I started using Libre. (I am quite obsessive about my BG control).
The only time there are discrepancies in readings are just after I start using it, it is usually 10 - 20% under, but I take this into account when doing the readings following a sensor change.
There is no problem at airport scanner security and I've never had any pain even when applying and no rash etc.
I've downloaded the app for the sensor to my phone so don't even need to carry a reader any more, the information on the phone is great, really well presented and easy to read.
One thing is be careful when applying sun cream, twice I have lost a sensor after applying sun cream then going swimming. I now keep lotions and creams well away from the site of the sensor.
The cost is the only down side but I think it is worth it for the amount of finger pricking you avoid and the ease of reading results and the insight gained.
I was given a good comment about diabetes control at my clinic.
'Diabetes control is like walking through a dark tunnel where you switch a light on 4 times a day when you check your BG. Having the Libre is like having a light on all the time.'
If you are thinking about it go for it, but remember each sensor is almost £50 and lasts 2 weeks.
