i bought a high end chi dryer from AnnMarie. I cringed at the price tag but every time I went in to see her, she used that dryer on me and I got no frizz as she was drying and my hair felt different. My old walmart dryer was kind of crappy.
So.... I really like the dryer. The only thing I don't like about it is that it doesn't have different heat settings. you either have heat or the cool shot button. I really like how it is made as far as holding the handle part. It is angled to fit your hand well. The cool shot which ends up being warm works well tho.
It came with a diffuser but I llike my old one better.
