I have recently been given a libre 2+ and find it very useful, although not particularly accurate, this morning before breakfast it showed 9.5, checked on my meter it was 7.5. It is very useful for showing you what your blood levels are doing, and how some foods affect your blood glucose more than others.
As a driver I find the low glucose alarm very useful in ensuring I am ok to drive. Personally I have not had a problem with sensors falling off, I always use a swab to clean the area before applying the sensor and try not to get it over wet when showering.
Unfortunately diabetes is a very individual disease and treatment is not a one size fits all solution (something I think a lot of so called specialist don’t appreciate)
