Featured review

Consistently poor blood glucose readings in the final 30 days of a 90 day supply. Constant loss of signal, constant notice of low blood sugars of 55 or lower when by finger stick the blood sugar is 135 or higher. Consistently poor manufacturing. the product does not do what you say it does in the final 30 days and thus cost me and my insurer time and money every time you put out poor product. This is a nationwide problem and you know it. Just terrible operation.
