Happy with the strength, speed, and multiple style of brushes

Oral-B GENIUS 9000 is a great electric toothbrush to properly clean your gum and teeth and so far, it does its job really well. It encourages me to do the 2-minute Dentist recommended tooth brushing (something that I normally couldn't be bothered doing) and also to properly clean each tooth.

I've had the Oral B Genius 8000 for about a month now and my, what a difference it's made to my teeth and gums. I believe the 9000 only has slight differences - colour and charging case(awesome idea). Otherwise they're pretty much the same.
