The thing about buying items from of Chinese origin is:
1) They are not bound by consumer protection laws, you roll the dice and take your chances with any purchase.
2)They often mis-state materials used, quality of workmanship, origin of materials and a myriad of other things in an effort to get your money sent to them. Getting your money back from them is often difficult or impossible.
3) They often have wide variance in quality control or none at all.
4) They often have no after sales service and no warranty, even if they say they do.
As for the counterfeit end of the deal..... everyone should take time to watch this:
