Honestly, I think it's amazing.

We have a teenager who's always coming or going, forgetting to let us know if we're running low on paper towels, laundry soap, etc. Having her be able to just push a button (and have subsequent clicks be ignored) would make our lives plenty easier.

This is great for Amazon too, as I normally wouldn't buy things like soap, laundry soap, paper towels there, but I might now.
