this review title is: a regular brush nothing special and the content is: this is just a regular brush i would say it works the same with and without batteries i was hoping the ionic effect would help to control frizz but i was wrong both the ionic and the massage components are not strong enough to have any effect whatsoever the only good thing i paid for this so its too much trouble to return it at this point will probably remove batteries and use as regular brush.there are other information for this review, one is this reviewer did purchase it and the other is 2 people think this review is helpful.
