Amazing for the price
This is hardly just a vibrating manual toothbrush. After using it my gums sting and tingle for a minute, so it must be doing something.  The rotating brush toothbrushes don't create that effect. The timer is also a great feature. The charger does not make a direct connection with the brush; it must be capacitively coupled AC that is converted to DC inside the brush. I haven't used the more expensive models, but this is heads above anything I have used before; and I guess that's the point. I would never have considered spending $100 on a toothbrush, and I'm sure there are many other consumers who feel the same way.
