i am in the process of returning it. the male and female side clearly does not match up. i used the recommended accessories parts link on samsung's website for this part because i was concerned that i may pick up the wrong one from an authorized dealer. my laptop is series 9 NP900X3A. dongle AA-AE2N12B/US. i offered to send pictures of the differences but the operator says she has no operational procedure to do that.
so i will not be able to use an Ethernet cable adapter. i can NOT give any real rating for this product as i was not able to use it at all. it doesnt fit my laptop. the recommended parts is wrong for this. make sure you can use it on your laptop even though it recommends it on samsung's website.
