Been using it the guts of 6 months now, would readings still be reliable?
I only ask because have had 3 "7+" 9am readings [normally only readings i check this past while]this week and yet my lunchtime pre was "5.1" and 2 hour post "5.9".
Is it the type that is callibrated everytime you get a new pack of strips? I have this type(Optium Exceed) and both of mine are still going strong after 3years.
It would be good if you had a backup - you could then check these aginst each other.
