Product review (4 stars): Works fine if you use it.
Using a marker I blacked out the words 'Dishwasher Alert' on the front of it as I felt it was distracting. I just want to know whether the dishes are clean or dirty and not reminded of the name each time. It works fine as long as you remember to slide it over each time you run the dishwasher. It does its job only if you use it so if you have member(s) of your family who thinks its too hard to remember to slide it well, you're out of luck. Recommended.
