Pizza Pro Slicer: Love It or Hate It?

The first thing I thought when I came across this Pizza Pro pizza slicer ($19.99) was genius!

Then I imagined using it. The scissored spatula looks like it might be difficult to maneuver. Also, what happens when you prefer a larger piece of pizza? Or when it comes time to wash it?

Still, it's an interestingly designed product. Has anyone tried it?
