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
