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 have been using these strips for 2 years. My last container out of 50 I have used about 25 and 9 of those have given a failure error even though the reservoir was completely full of blood. I have tried these in both my meters and had the same defect of giving error codes and not wanting to turn the meter on without manipulating the test strip. I contacted the manufacturer and they were completely unwilling to replace the defective product until I sent back the defective product and they verified through investigation that the product was actually defective for a medical product required for those individuals that purchase it to live. I will be finding a new vendor to order my diabetic testing supplies through.
