All meters get bad and good reviews. They all have to conform to the same same accuracy standards before they can be marketed. I use the Codefree and have done for well over 2 years. Yes, you get an odd rogue reading, and sometimes a whole pot of tubs can be variable, but these aren't general. I think it is a good little meter, and as I use a lot of test strips I appreciate the small cost compared with other meter strips.
