Hello: I guess I was mistaken about these strips. I have changed my rating from 2 to 4 stars. I bought the Relion brand meter and strips to compare with these G10 strips and G10 meter. While I did have a wild card a few times with these strips I am assuming for now that is just me and not the strips. I have compared quite a few results amongst a couple of these bottles and the Relion brand and they are within six or so of each other hi and low.
