Review (4/5): Good enough for the price, but not perfect
Pros: Nice and flat head is great for weak waves & getting right against the scalp.
Folds really flat for travel or if you have limited storage like I do.
Seems to spread out the air better than the free diffuser that came with my hairdrier.
Cons: Likes to fold while being used. I've taken to holding the drier in one hand, the end of the diffuser in the other to keep it from collapsing at the wrong time.
Doesn't fit "every" drier & the opening isn't very stretchy. Seriously had to have my 6'3", giant handed boyfriend get it on & it still took him 3 tries. Needless to say, it's never coming off now!
