I have always packed my hairdryer and diffuser on trips, and looked for another solution before an overseas trip because buying a transformer and adapter was going to be expensive - and I still wasn't sure it would work.  I got this, and heartily recommend it.  It fit on hairdryers in 3 different hotels - one of them was kind of wide but the material on this diffuser is forgiving enough that I was able to stretch it around that one too.  I will now pack this instead of my hairdryer even for quick domestic trips, what a nifty travel solution.  And I have curly hair and am kind of picky about my diffuser - this is sturdy (even though it's collapsible) and full size.
