Ordered a watch from "Mi Global Zone Store". Decided on a better more expensive watch from the same store and requested cancelation of the first order within 90 minutes. 10 hours a later received email that it shipped, and didn't get a response from the seller for 3 days, only for them to say "sorry, we didn't get your request in time. No return for refund". Thankfully, the watches both work great. Absolutely no buyer protection, despite what AliExpress says... Beware. Deleting immediately.
