Newbie, created Word Clock, but time is not accurate (clock is slow)

AliExpress has dispute resolution mechanisms, but awkward. Nevertheless, I have successfully fought and won some rip-off deals, full or partial refunds the result (because of course the return postage is 100x the other direction).

But such efforts are hardly worth my time. I just try to figure out what red flags I missed...

Ordering from China is the only practical option for most people living outside the continental USA or maybe parts of Europe. None of the American or European companies can ship anything to me for anything less than several times the cost of the devices. USPS can do it much cheaper for them, but they don't seem to care.

Since the pandemic began, all shipping costs have increased across the board.
