A lot of negativity in the comments, I'm surprised. Electric toothbrushes aren't more effective than traditional (http://en.wikipedia.org/wiki/Electric_toothbrush), but have huge sales numbers.

Packaging is a problem right now, but put that thing in something unapologetically plastic and shiny and there may just be a market.

There's a key qualifier: "assuming that the person using the manual toothbrush will brush effectively". I have a huge amount of trouble brushing effectively with a manual toothbrush; with an electric I can just let the toothbrush do the work.

Good point. That should be noted and it also furthers my original point: This new device claims an even simpler and shorter process.
