Product review (5 stars): Great Dishwasher alert
This is a great dishwasher alert if your dishwasher is not metal that can typically use the magnet type.  It is adhesive so you can stick it anywhere on the dishwasher.  I have mine right next to the buttons as you pull open the door.  It's very nice looking and it blends well with my dishwasher.  It looks like the alert came with the dishwasher.  All you have to do is slide it to clean or dirty and voila!  I would recommend this.
