I am diagnosed with T2 a week before. I first bought abbott freestyle optium and I was satisfied with it as I made my blood glucose levels under control (75-180).As the strips were expensive, I bought sd codefree and compared on both. Sd codefree always give higher readings (15-25 points more) as compared to free style. The readings arent consistent either, first I got 136 and then 134 and then 122 and then 130. Kindly help me and share your experiences with it.
