The good: Items usually arrive within 2 weeks, some within 4 days. If quality is bad or defective, they refund. You do have to show the damage with pictures. If product costs just a couple of dollars, you don't have to return it. I have returned a couple of jackets in the 20 Dollar range that did not fit and return shipping was free and I got refunded within a few days of returning the jacket. I always use paypal and only had to use paypal once for a refund when AliExpress denied my (legitimate) claim. I think AE really gives good buyer protection. Also, I had a great experience buying a laptop screen on AE. I could not find the exact screen on ebay or amazon, had to return two because they did not fit. By contrast , the AE seller knew what he was doing: I sent him exact specs and pictures and received a perfect match within 10 days, solidly packaged. I was totally pleased. The bad: Some item descriptions are incomplete, unclear, hard to figure out the specifics of an item. Worse: Some sellers advertise items at a low price they never actually have and they know it. I bought a zizzo liberte bicycle for around $300, the description said it would be delivered from the US with 10 days. After 10 days of no shipping, AE cancelled my order automatically and immediately refunded my money. The seller never had the item to begin with, yet continues to advertise it. Because AE cancelled the sale, there was no option to leave a negative rating for the seller, so other buyers continue to be promised something the seller has no intent of shipping. Luckily, AE now has pretty tight consumer protections in place and luckily I was not out any money. AE needs to kick these sellers off their platform and include an option to leave feedback as a warning to potential buyers. See their ad DUTRIEUX Sports And Outdoor Specialty Store.
