Q: I ordered the Sony 4Pin to 4Pin Digital Video cable for my Sony digital camcorder and it came with a bent pin in one of the connectors. I specifically ordered the Sony rather than a generic one because I thought it would be more likely to be of higher quality. It was advertised as new. When I plugged it into my camcorder it did not work. On examining it I found that it had a bent pin. When I looked at the camcorder connection I found that the bent pen had ruined the connection in the camcorder. What a bummer. I contacted the seller and they were willing to send me a replacement for the cable but took no responsibility for the defective one ruining the camcorder connection. I did not bother to get another one for obvious reasons.
A:
Negative
