This site is full of merchandise to purchase however, many of the merchants on this site provide false advertising, ship out something different then what you see in the picture advertised, or they ship out defective product where you are stuck with having to incur additional costs to ship the defective goods back, most merchants on the site do not cooperate with refunds for their defective goods. Furthermore, Alibaba.com's dispute department is useless as they expect you to also incur further costs of inspections even when you have produced your own technician to inspect and report they only accept their own inspectors making you have to pay. It's ridiculous. I recommend going to reputable businesses rather than this site as good proper businesses will take back their defective goods at their own cost and refund the clients.
