Product review (5 stars): Simple Solution that Works
I wanted something discreet, something that would keep me from killing my husband for putting dirty dishes on top of clean ones, and this item works great for that purpose.  The husband is still alive.  We've had this a few weeks now, and I'm training husband to use  and see this.  You cannot see it when the dishwasher is closed because it fits in the space between the top of the dishwasher door and the underside of our kitchen countertop.  It attached via glue strip.  It feels firm and seems as if it will stand up to the action of sliding the little plastic door left or right as dish status changes from dirty to clean.  I like how this works--it's a simple solution.  Why spend more for something large to stick to the front of my dishwasher that will be in the way when I'm cleaning?
