1 is a high-end instrument of Johnson & Johnson series, but it has no functions such as color screen, automatic strip withdrawal and one-button navigation (the instrument is equipped with operation color map).

In addition, the memory capacity and test time have also increased.

2 the price is poor, and the price is half cheaper than the best.

But the test performance (accuracy) is not much different.

In a word. Buy expensive ones if you have money, and affordable ones if you have no money.
