Review title is Doesn't fit a 2-inch dryer [SEP] I measured my blow dryer before I ordered this diffuser, because at the time the description said it would fit a 2-inch blow dryer. It doesn't. Not even close. Nor does it fit my other blow dryer. It also doesn't screw on as the description says. I suppose if it did fit as advertised it would work as well as any other diffuser.
