Product review (5 stars): Finally found what I was looking for!
I thought all stoppers would be standard-- they are not!  I went to Home Depot to find a replacement for my Waste King stink stopper/Splash Guard.  Needless to say it did not fit and I had to contact Waste King.  They told me what I needed and sent me to Amazon to order it.  I ordered on Thursday afternoon and it was here within 24 hrs. I love Amazon!
