Alibaba tries to be very helpful but they let anybody sell on their platform, there are total scam artists who will send you partial orders and then try to receive more shipping fees, Alibaba is very slow in resolving the issue and the language barrier through customer service and the sellers is very frustrating, beware who you buy from I've had some good sellers but they're hard to find
Tip for consumers: Research the seller and the products they have sold to other people be wary of fake reviews Alibaba lets anybody sell on their site it is very hard to find an honest person but there are some on there they are just hard to find
