Product review (5 stars): Perfect for us!
We are renting a house and the dishwasher was missing one of these, I took a shot in the dark by guessing that this might work in the Frigidaire dishwasher we have in the house, and it is perfect! Crazy how NOT having one of these really sucks.  We got a 'temp' from a family member but it was from a different make dishwasher and it really wasn't ideal.
