If you're looking for more information the Oral-B you should give www.Amazingtechproducts.com a visit. I stumbled upon the site when I was shopping for a tooth brush and they had a good product demo video on there. If you're on the fence about buying it, or you just want to see how it works, it was a really cool option. It's one thing to read a bunch of reviews about a product, but it's another to see it in action and find out just how well it works. It made my shopping for a digital toothbrush much easier, and it might help you too.
