Product review (5 stars): Simple is better
This speaks for itself.  I got a distress call from my brother after he remodeled his kitchen and replaced his appliance.  The dirty dishes indicator I had given them went out with the old dishwasher.  And they only wanted the same one.for the new kitchen,.

It's simple, straightforward and functional.-- no cutesy or flowery statements.  blends into the background and integrates itself as an utensil.

The adhesive (obviously) stays put for years.making it more practical than a magnet, actually. Since you won't be using it on another appliance, the permanence is not  a  deterrent.
