Of all the diffusers I have used (either ones that come with the blow dryer, or those I've purchased separately), this one  is by far the best.  It is there best combo of letting enough heat through without too much gust of the air to create frizz.  I haven't had a problem with it collapsing while using as others have mentioned.  It is wonderful for traveling, but is also just my every day diffusing powerhouse.  Curly haired girls, look no further!
