So sad it does nothing a normal cheaper brush wouldn’t do [SEP] Oh no! I had such high expectations for this to help my daughter with her tangles. It is nothing more than a brush that waste batteries. It did nothing for frizz with the ionizer, it did nothing for the tangle with the vibration. There is a light on top of the brush and the sound of vibration but nothing really happens except noise. I guess you could say it did something if you took way too long to brush through a small section of hair. Which I think if you took extra time with a regular brush it would do the same thing. Going to return. Complete waste
