Q: Why we find some prices are very high compared with some other supplier, and from the picture or it's parameter, all looks the same?
A: As China is still a developing country, there are only a few products with patent rights, and copy products l spread very fast in the market. Of course, the prices of those copy products with cheap material and less quality control are relatively cheaper.
