Review (5/5): Great diffuser for great curls
I love this diffuser. It fits perfectly on my hairdryer and I've had no problem with collapsing or falling off. I smoosh my hair in and I get perfect curls. There is a learning curve, as with any new product but I love it. It gives me volume with no crunchy curls. I don't press hard on it, just push my curls in and let it do the work. It does collapse down which makes it great for traveling!
