First, I should note that I don't do well with my hair. I have thick long hair and what impressed me first is the minimal time (3-4 minutes) it takes to dry it. As for the attachments, the best for me, who doesn't handle them easily, is the one that straightens the flyaway hairs, it's like a cylinder and you just touch it to the top of the head and bring it down. As for the rest, I don't have an opinion because I need to practice. However, I don't think they are particularly difficult to use.
