Wow! This tool is amazing! It is so much easier than trying to use a brush with my blow dryer. I am middle aged i'm going through menopause. My hair has gotten very dry and frizzy looking. I don't often want to take the time to style my hair, which is another problem. This made it quite easy. I press the button on the top and the tools  pop off to switch to different brushes. My favorite might be the volumizer, although the straightener is nice as well. The straightening piece has metal along side of the comb which heats up and helps straighten my hair. My teenage daughter has grabbed this from me on more than one occasion. She also thinks it's fantastic for her very long hair to make it smoother. I would say this is absolutely worth the price and a phenomenal tool. Way easier than using a blow dryer and a brush, which is what I have been doing for over three decades.
