Simply put, I was very disappointed. I ordered 3 pop-up sink drains and received 5. In addition, I found I didn't need them since the faucet I had ordered included a pop-up drain.  I contacted Kraus and they seemed concerned and sent me an email detailing what I should do. I sent them a copy of my purchase order and have never heard from them again. I will not purchase Kraus products ever again.
