Trade assurance only seems there to pacify customers concerned with importing, but it proved to be completely useless for me. The seller knew what words to say to throw the Alibaba representatives off the trail of facts. My particular item was not damaged in transit and this was admitted to by the seller in the Alibaba chat where I kept all of my messages due to the constant warnings from alibaba to do so. I went around in circles with alibaba and they continued to ask for more and more proof no matter what I supplied. Needless to say it was an exercise in futility.
I feel really bad for the people that buy container loads of stuff and get screwed.
"Zhenglong sports utinsel company" and their sister company / broker "Wuyi smart vehicle company" are the company I purchased a sample electric ATV from. There were so many things wrong with it, from broken and sloppy manufacturing, to parts that appeared to have been laying around a warehouse and then thrown together (they were scuffed, dented, chipped, and rusting). That said I would have a useless pile of junk if I did not happen to be very handy with everything from welding, to rewiring electronic circuits, and generally able to fix all of the issues that the item shipped with. I also had to be able to source bad parts from other places. This "sample" is completely useless as a sample product for which I intended to resell on a volume basis.
Sourcing from Chinese suppliers and manufacturers via Alibaba is useless due to the extremely poor communications and/or translation software. China will not be a viable country to source products directly from as long as there is this poor communication and poor quality control. At this point anything I source for resell has to come from a third party (if it comes from China) that does their own quality control and has easy to understand fluent English-speaking representatives.
