Well if it's just the bog standard gluco navii..
I use it & it works fine
Smaller blood sample
Means fewer errors, less wasted strips .
And strips are very cost effective
When I began looking for a meter, I noticed many are focused on accuracy
Whereas, with the inbuilt error of all meters ..I personally thought trends more important.
So accuracy while nice, didn't outweigh the help of knowing if I was trending down or up offered.
And given none are truly accurate, it seemed a very unbalanced cost ratio.
Sure others will disagree
But for me....well done.
It's a good choice.
Nb The gdh part when googled takes me to NFC version, & of that I know nothing .
