Product review (5 stars): Perfect. Brilliant design.
Best kitchen gadget for a household of boys that can't tell if the dishes in the dishwasher are clean or dirty. I've tried other ones, and they fell off or no one used it. This is one is solid, and you stick right on the dishwasher and it doesn't fall off. The notification bar slides from one side to the other. Very quick and easy.  I know it sounds silly but it really is one of my favorite things. I haven't any rewashing issues since it went into use.
