The brush has special vents that allow air to flow so hair dries faster. Plus, it's quicker than using a dryer and then a flat iron or curling iron, which equals less heat damage.
Promising review: "After reading review after review I decided to give this hair dryer a try. What can I say — best decision ever! As you can see from first picture, right after washing hair, no products or anything, my hair looks absolutely awful. After not even 12 minutes, dividing hair into sections, my hair looks like I just left the hair salon. And the best thing is no effort at all! I have never been the best person at styling hair, but this tool...this bad boy sure worked magic!!! I'm 100% satisfied with it. My hair looks healthier, shinier, and feels softer to the touch. I am never going to use a flat iron again!! Thank you Revlon!" —Amazon Customer
