I brought something from Aliexpress a couple of months ago. I didn't have any problems with the product or shipping.
I did get a phishing Postal fail delivery notice scam at about three weeks in with all my shipping details in the email. Then after a month my credit card got fraudulently used. I told Aliexpress and closed my Aliexpress account. Not sure who was to blame (Aliexpress or vendor) but does it matter when it comes down to your personal financial security?
