tl;dr: Very cheap shipping, long shipping times, sells things that are hard to find elsewhere, mixed quality of products because they host third party vendors. Was satisfied with experience, knowing these things. I ordered a product from China that is pretty hard to find online, only found it on this and a couple other sites. The others wanted to charge $20 for shipping, AliExpress charged less than $5. DO NOT expect your order to ship from China to US in a week, mine took almost three weeks. (This was also how long the other sites said they would take, so, not surprised.) Additionally, double check the individual vendor, some are good, some are not. My order turned out great, but I definitely believe all the people leaving 1 and 2 star reviews on things that turned out to be bad quality. I hope they left a review on the vendor's page, I don't think AliExpress does much vetting so it's up to us to look out for each other.
