Yeah well my AliExpress NUC was stolen from me after I shipped it back for repair and never heard back. Was also a bios problem, black screen on boot a day after I received it. Aliexpress and the seller ignored me over multiple months and many messages. $600 lost.
That’s why you use a credit card. Just have the bank issue a chargeback.
That said, I agree that AliExpress is way more stingy with refunds compared to eBay/Amazon. One time it took me 4 months to get a package that would normally be delivered in 10 days to the US. Any normal website would have just issued a refund after 30 days. Still, AliExpress is incredibly cheap and I’ve bought a ton of assembled PCBs from them that are either impossible to find elsewhere or only available with a 10x markup.
