Good, collapses while using
The first time I used this diffuser, I hated it and was positive I would return it.  It constantly collapsed against my head as I was drying my hair.  I spent more time pulling it back apart than drying my hair.  Now that I've used it 5-8 times, I've gotten used to it being so easy to collapse and don't press it as hard against my head.  It still collapses partway sometimes and that is annoying.  I do like that it is easy to travel with and honestly my hair has never been curlier.  Not sure if it's the new product I'm using (LUS Brands for you curly/wavy haired folks), but I'm going to keep giving this product a chance.  Will update review if anything changes.
