Are blood glucose measuring devices expensive? What brand is better? How much does it cost?

That depends on what brand, depending on what you buy domestic or foreign, I bought for my father is the Sanno blood glucose meter, high accuracy operation is also simple, the old man on the hand are very fast, the key is the supporting test strips are very affordable, with a little bit of heartache. And because the consumption of test strips is the largest, so the overall comparison, Sanuo cost-effective.
