I'm quite impressed by the technology that the Oral B genius has. - It really is the future, and with the Oral B genius, the future is really here & now. - Not only the technology but also the care of dental hi genie. - If you really care about your dental hi genie, than the Oral B genius is exactly what you need. This is my review - I don't like writing too much, so that is the only reason my review isn't very detailed.
