To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I am disappointed in the number of duds I get when trying to use these strips. When they work, they work well, but when they don't, I have to start over, causing another prick to the finger and that is unwanted. I have been doing this for years and this brand just isn't consistent.
If you are considering buying these you need to consider that only about 2/3 of the strips actually work. Another consideration: I just tested my blood sugar (I'm diabetic) and it was 23, which means that as I am typing this I am likely unconscious -- likely will not buy these again.
