I can't vouch for the accuracy, one way or the other. What I can say is that I have found nothing more affordable. These are more affordable than me getting strips through my insurance. Because they are so affordable and purchasable without a prescription, I can take a reading whenever I want without worrying about having enough or the cost. I can run experiments seeing how certain things affect my blood sugar. In fact, I have run tests and discovered that the meter for these strips can actually measure drinks and detect if they are diet or not.
In an age where Walmart is constantly under attack, I very much appreciate that they make medical supplies so affordable, especially for those that can't afford it.
