Since aliexpress is a website for all kinds of merchants selling stuffs, you are bound to meet a bad one, like ebay.
Aliexpress offer buyers protection, but their protection is quite useless if you don't monitor each and every purchase carefully.
Since shipping always takes a long time, get delayed or go missing, you have no idea, but wait.
Then the protection runs out and your "protected" money is gone.
Unless you track your purchase everyday and make a dispute before it ends.
Or else good luck to you.
When I make a complaint to aliexpress, they tell me to buy from seller with good reputation.
Well, this one has "good" reputation, but when things go wrong, the shipment ended up returned to them, they have so far refused to return my money after repeatedly messaging them.
I've considered my money lost due to unscrupulous seller.
The seller is AUTO SUPPLIES SHOP Store No.521062
Do not buy any items from them, unless you want to test water with your money.
