This weeks contestant: The Scotch-Brite Soap Dispensing Dishwand, by 3M
Official website

The dishwand is designed to hold soap within the wand and dispense the soap through the sponge upon scrubbing. If you look at the picture to the left, you will see the big blue dot in the middle. It's actually a plug that acts like a pump, or a primer (see lawnmowers, human-powered). I assume that is maintain some sort of pressure on the soap.
The Good: The scrubbing brush at the end provides a great tool to wash dishes without the use of a worn-out, dingy dish rag. With the soap being constantly present within the the brush, it stays clean. Another
advantage of the dishwand is that the brushes on the end are replaceable. You don't have to buy a whole new wand, just the replacement pads. Sounds easy, sign me up!
The Bad: Ugh, where to begin. There isn't too much, honestly. Just. One. Major. Design. Flaw. The blue bulb. If you're washing a glass or cup, and the bulb pops out, just throw it away. It's designed to come out, I guess. But once it comes out, it will not stay in for nothing. You can't even pay it to stay in. And the way it's designed, it does not fit easily into cups. The lip of the cup usually scrapes at the bottom of the bulb, popping it out of place, and making it a hassle to use forevermore. And since the bulb can easily pop out, soap can leak ou - errrr, pour out easily. And that is a major design flaw.
My wife loves these things. Every time one breaks, she'll go buy another one. And the next one will do the same thing. It's guaranteed to break, like the sun rising.
My opinion: Don't buy it.
