Product review (4 stars): Color is off, but form and function are perfect.
The dispenser works great and was an easy 10 minute install. Out old one still dispensed detergent properly, but the rinse agent side had one of the tiny round windows come out, so the rinse agent would just run out and the rinse agent side of the dispenser wound up filling with water. If you are like me and don't care if rinse agent is used, then this doesn't matter. However, if you are like my wife and you can't stand the feel of the dishes that have come through the washer without the use of rinse agent, then it's an issue which must be dealt with. :)

The new part appears to be factory original, sealed in the box with the part numbers matching this listing.

The only reason I'm rating it as 4 stars is because the color of the plastic didn't match the pictures in the listing (which look just like our old part). The new part is gray with darker gray instead of white with blue as is pictured. Likely no fault of the seller, but I assume that Whirlpool just changed the color of the part without changing the part number. Whatever. It still fits and works great and was the cheapest place that I found the part. Just be aware that the color may no be what you are expecting, if you care about that sort of thing.
