Is it worth purchasing the ali express plugin?

I want to start my own online business but am a bit hesitant of some issues I have come across. I have heard about the aliexpress plugin and do want to sell a few ali express items in my site, but noticed it does not support seo functionality for items. For example, most stores that use the plugin that have been created by users on this site only have specifications of items in their description and nothing much more that merits on page seo. Am I missing something? Also, are there other plugins that work just as well as the aliexpress plugin that can allow me to import items from aliexpress, amazon or ebay without having to manually import them all? And finally, if a customer purchases an item through the use of the aliexpress plugin, would they end up depositing money into your account straight away to which you can then purchase their item in aliexpress or would they end up being contacted by the dropshipping company to complete the purchase?

I have heard some sad stories of customers purchasing items from websites that import via dropshipping companies who then send products with their own labels. Obviously the process makes you look unprofessional. Customers end up getting angry and seeking a full refund as well as giving a negative review. I just don't want to end up like that, so I am hoping some here can help me with their experience. Thanks.
