1, compare commodity prices. Commodity prices are ridiculously low, which is out of line with the industry average and cannot be considered. There are two situations for such goods, one is that the quality is not good, and the other is that the goods have no after-sales guarantee.

2, look at the single product evaluation. Looking at the evaluation and follow-up of photos, the credibility of comments is high. Different consumers have different evaluations of photos, and the physical pictures have no logo or information unrelated to the goods.
