As others have said, there are a lot of people who love the Libre.
I was able to trial it for a couple of weeks and was disappointed: I felt it was not reliable. The two problems I experienced were incredibly high readings (3 - 4 mmol/l higher than finger pricks) and it fell off after 2 days (I was very lucky to get a replacement).
On the other hand, once I got my head around the Libre readings being 10 minutes behind the finger prick, I found the arrows indicating whether my BG was level, rising or falling useful.
Two things to consider if you treat your diabetes with insulin:
- the DVLA will not accept a Libre (or CGM) reading prior to driving
- i was recommended not to use the Libre reading to estimate my insulin dose
If you are able to get a free trial (mine was arranged by my diabetes nurse), I recommend going for it to make your own decisions. Reading about it is one thing but not a substitute for seeing and playing with it yourself.
