Review (1/5): Does not stay on the hair dryer!
This diffuser is awful. The description says it will fit almost any dryer. I tried 3 different hair dryers and my friend tried it on one of hers. It did not fit ANY of them. It would either not go on at all or else slip right off. Do not waste your money on this. I didn't try it when I first got it because I was going to use it for travel. When I discovered it didn't work it was a couple of days past the deadline to return. It's going in the trash.
