Product review (5 stars): So Simple, why didn't I think of that....
I got these today, well ahead of the actual shipping delivery date, so cudos for the fast shipping.  The brackets look very simple, and appear to be something very easily installed.  I was a little surprised how small they actually were.  Only a few inches of thin bent metal with holes for mounting, along with four screws and four plastic hole plugs.  A little pricey for what you get.  I could have made these myself very easily, but now that I have them, I'm gonna keep 'em and put 'em on.  I thought they would be more complicated than they actually are, so I was a little surprised.  I wish I had just waited till my cabinets were in and took a good look at how I could side mount my new dishwasher, cause I could have come up with this stuff on my own for about two bucks total.  Live and learn.
