After the first time trying this, I have to say that I am pleasantly surprised!  I was a bit skeptical that it would dry my hair that fast. I do have somewhat longer and definitely thicker hair (especially since I have not had it cut for while sometime due to the pandemic). In 8 minutes flat, my hair was completely dry and that was even giving it a cool burst at the end for about 30 seconds. I did section my hair off, since that is normally how I blow dry my hair, but it was definitely a much shorter time of drying than my old dryer. My hair was super smooth, and it stayed like that for the entire day. Most of the time I have to run a straightener over my hair to keep it straight, For this review, I kept the straightener off to see if my hair would stay smooth all day, and it did!
