A regular brush. nothing special
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 $6-7 for this, so its too much trouble to return it at this point.  Will probably remove batteries and use as regular brush.
