I have just bought the SD Codefree, after the two hour post-prandial test, I used first the SD Codefree, then the Contour next meter, the Contour next was higher by 0.2 on both occasions which seemed OK by me.
I have just bought the SD Codefree as my GP practice has decided to remove test strips from my repeats. I have to say that I amazed at the price difference between SD Codefree and bayer, just under £12 for a tub of 50 strips and 100 lancets, the VAT already removed two days for free delivery, where if you order anything from bayer/ascensia you can wait week's and they charge about three times more!
