If you have ever used Freestyle Libre’s first edition, please let me know your feedback.
In my case, the readings when compared to my gluco meter showed around 20 mg/dL lesser on the sensor. This was true for the first five days of use. Then suddenly, the sensor started showing readings that were 50% less as compared to the glucometer.
I used the Libre1's for about 3-4 years - I normally found they were about 1-2 mmol/L (18-36mg/dl) out for me, but they were consistently out so I could tell what I was out once I'd got through the first day
Note, I never got to try the Libre2's as I got moved to a different one that works with my pump instead before the Libre2's were available
Oh, I forgot to mention in my reply - they were a complete game changer for me - got my HbA1c into decent number (previously had not been lower than about 58 for my entire life - mostly 65+) - the libre 1 helped me get it down to 43-46.
I feel lost without a sensor now
