I love you so much I bought two. This Revlon lonic Hair Dryer Brush still has a lot of life left in it. I've thoroughly cleaned the bristles in each dryer head as well as the outside of the device. It features three heating settings (high, low and cool). And three attachments a 1 inch, 1 1/2 inch, and concentrator to reduce frizz. Questions? Leave a comment below!
