Hi I have just purchased to gluconavvi meter as recommended as test strips are cheaper. I also got the contour next one free. Checked my blood sugar at 8.30am and was 8.5, then checked at 10.30 2 hrs after I ate and gluconavvi one says 7.4, thought I would check the contour reading too just to make sure they were the same. using the same blood sample the contour reading was 8.7? Has anyone tried 2 meters before and noticed any difference? Just diagnosed a month ago and want to get these tests right. Want to stick to the navvi one as cheaper for strips, thanks
