Review (5/5): Works well, stays on the blow dryer without falling off.
So far I am enjoying the Curly Co. collapsible diffuser. The diffusers that come with blow dryers always seemed to fall off, and they took up so much space in the drawer. This fits nicely on my hair dryer and collapses when I want to store it, and I don't even remove it from the dryer. The diffuser works well and my hair seems to be fluffier ,with defined curls, which is always my goal. I look forward to being able to take this with me when I travel, so that is a nice bonus.
