Doesn't fit (most) dryers [SEP] I bought it specifically because so many people were saying it fit their dryers that were my brands. Unfortunately I got it, took it out of the box to look at it, didn't realize my husband threw away the box when I wasn't paying attention, and by the time I got it into the bathroom a day or two later and check if it fit with my blow dryers I didn't have the box to return it. I have three completely different hair dryers, you would think it would've fit at least one? Nope, it didn't fit any of my three blow dryers. I have a vidal sassoon, conair, and a Revlon. Again, they are all different and different sizes too. It did not fit any of them!! I offered it to my friend, I said just bring your dryer over tho to test it first. Hers (different than all mine) didn't fit either!! I walked it over to three different neighbors and None of theirs fit!!! I am so curious how this is fitting so many other people's? Is there an attachment needed? I am very dissapointed as it was not cheap. So now I'm out the money plus I still need a diffuser and this thing is rather large and taking up space in my drawer because I don't like throwing away anything new. Be careful when buying it, apparently it doesn't fit many dryers at all.
