Product review (4 stars): stop people from putting dirty dishes in my clean dishes
This two sided-magnet will, hopefully, stop people from putting dirty dishes in my clean dishes.  We throw a many parties and get-togethers almost every weekend.  Our helpful guests put their used dishes in the dishwasher, but don't always notice that they are sometimes clean - meaning I end up re-washing an entire load of dishes because I cannot always be sure what was dirty, what got dripped on, etc.  That's a waste of time, water, and dish soap.

It's black and white-ish.  It would be cool if it came in different colors.  On mine, the "dirty" side was a bit scratched up when I received it, but still usable for it's purpose - keeping observant people from messing up my kitchen.  Are you getting that this is a real pet peeve of mine?

It magnetized perfectly to my dishwasher.  I even accidentally dropped my dishwasher door too hard and didn't fall off, so it's a decently strong magnet.  Not all dishwashers are made of magnetic metals.  This is not the fault of the magnet if it doesn't magnetize.  Be sure to test your dishwasher with another magnet before ordering this one so you don't end up disappointed.

So, I gotta get back to my Sunday chore - clean dirty - dirty clean.

The only improvement I can see, other than more color choices (and possibly better packaging to avoid scratches) is if the little butler actually did the dishes for me :)

While I was sent a free sample, this is my own opinion.
