There is far more to www.diabetes.co.uk than this great forum with great contributors.
If you go to the Home page, there are lots of diabetes related articles which are well organised and easy to navigate.
There, you will find many answers to questions you have and question you haven't thought of yet.
Thanks that is helpful. I have some questions please:
1) It says the monitors are approved for 6 days of usage etc. What's the point of using them for 6 days only? So you cannot use them for life every day?
2) It says it measures interstitial fluid glucose and not blood glucose. The former lags compared to the latter. So what it happens if you read a high interstitial glucose and you get insulin, while your blood glucose is low?
