Electric toothbrushes aren't more effective than traditional

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.
