Yeah, i took a risk on a 0 feedback seller in mainland china and got stung.
Not a big deal since the initial cost was relatively low and i got the money back from paypal a day or so after i asked.
Took the chance since it listed for $35 instead of the usual $50. Thought there was a chance it was legit since it wasnt outrageously cheaper.
I have purchased a ton of random stuff from china, taiwan, and indonesia.
Spacers, cable ends, housing stops, cheap tape, jr mtb bars, and more. I just bought some microshift STIs from what i think is mainland china.
All of its been delivered in good time and is of the quality i expect for the prices i paid.
I dont see a reason to ban that entire part of the world just because some scam.
