Unlike some other reviewers I did not notice that this part was too flimsy or the jumpers were too thin.It looks alright to me and seems an exact fit for Polk ES50 (and probably other floor-standing speakers).I just wish it was packed better because internal contacts for soldering were slightly bent when it was delivered to me. It cannot possibly affect the performance though.So if you need a replacement part for Polk speakers, this is a good inexpensive choice.
