I have had multiple meters and my all time favorite is the one touch ultra. Second is the accu-check active.
What is your favorite, and why?
I like the one touch ultra, b/c of the 5 seconds it takes to get the test result and I love the size of it. The case was also convienant to put drivers lisense or anything else in the little pocket, it came in handy on my honeymoon to carry my money in.
The accu-check I like also because of the speed, I just wish it was a bit shorter.
