Doesn't fit some dryers
Bought this for travel because it collapses. It fits on my home hair dryer fine and works well. I wanted it for travel tho, so I wouldn't have to pack my large dryer with that big diffuser. Problem is, it didn't fit on the hotel hair dryers, on two different trips, with two different types of dryers. One was a small travel size, the other a standard large dryer. I was not able to get it on either of them.  So I'm disappointed that it defeats the purpose of this diffuser.
