Good Evening, I am on my third ever freestyle 2 sensor and yet again it is not working at around day 9, constant retry in 10 minutes messages, it is very frustrating, Abbott have been good with replacements, but I don't like keep pestering them, but if I don't ask them it will not work in the long term as NHS prescriptions only allow 2 sensors per month so the whole thing will go out of kilter. Abbott kind of said this is isolated but what are the chances really. I was doing comparisons with my Accu Check Instant but got a bit of a ticking off from the DSN nurse, she said stick to the Freestyle, is this a common theme folks.
