Okay diffuser
Like other reviewers have said, it collapses when you use it and it didn't fit my hair dryer with a 2&#34; diameter. I assumed it would since the description states theirs is 2.25. With some work I shoved it on. As for the collapsing, I just used my other hand to hold up the diffuser but it still doesn't work like I hoped. I'll keep it since it's great for traveling.
