Product review (5 stars): FINALLY! A dishwasher indicator that works!
This is the best of all the options for the dishwasher "Are these dishes clean?" dilemma.

 - It has double-sided tape instead of a magnet so it will stick to your stainless steel dishwasher just fine.

 - It stays firmly set to "clean" or "dirty" ... no accidental changes every time you open the door.

 - It's fairly thin, less than 1/2" so mine is actually installed on TOP of the door between the edge of the door and the countertop. This way it's not ugly and obtrusive on my pretty stainless dishwasher :-)
