Very dishonest buyer, he ordered wrong item but claimed the item seller sent is defective
Of courses the item cannot work on your device,became it is not for your device.

After seller carefully explain the details of why he ordered wrong item,his reply seems to like avoiding all the points seller said,and look the other way to his own mistake.

He even saying he is a expert and has experience something like that. And saying if there has mistake,that is only possible that is seller's mistake. What kind of expert would made that kind of mistake，and not able to understand what seller explained，after seller explain him twice about which part is his mistake. So he is pretending to be a expert ,However, his conversation revealed that he completely lacked basic professional knowledge.

It is so hilarious, because seller have asked him to provide the information of his device,he did tell seller the information,but the information he provided is already the hard evidence proofs he ordered a wrong item, his ordered a totally different item.
The conclusion is uncontroversial and conclusive. It was he who bought the wrong thing. He made a mistake.
However, he has been kept sophistry while facing the evidences.
