The quality of the brushing is impressive. I've used multiple Sonicare's for the last decade, My last brush eventually eroded so that first it became noisier and then finally the brush would no longer clean as well. But nevertheless I do not ever remember getting as good a cleaning as this generation. I like the idea of a USB charge for travel. Other bells and whistles are not as necessary, but I may become more beholden with them with longer use.
