I’ve actually tested a few different shipping methods from AliExpress for small electronics and craft supplies, especially comparing their Standard Shipping to USPS when available. My experience is that AliExpress Standard Shipping tends to be less consistent — it’s okay for non-urgent items, but yeah, tracking can be vague once the package leaves China. With USPS, I usually get better updates, especially once it's inside the U.S., and faster delivery if the seller supports ePacket or direct USPS shipping.

Also, if you're curious about how USPS tracking works when you're using it for AliExpress or other international orders, this tool is super helpful: en/courier/usps. It breaks down each tracking status and supports global packages too. I actually found it more accurate than the AliExpress app for U.S. deliveries.
