Great for travel!!
I've been looking a long time for a good diffuser to take when I travel.  Most were way too large and never fit the hotel hair dryers, and the sock diffusers never worked well for me.  This collapsible one is great!  I couldn't believe that it actually fit my small travel hairdryer, it was a little too snug at first, so on the inside of the rubber rim I trimmed off a little of the black rubber tabs and it fit perfectly!  I especially like that the diffuser nozzle is rubbery and clings to the end of the hairdryer instead of shooting off the hair dryer like a rocket. I'm also thrilled that it's collapsible and doesn't take up a lot of room in my travel bag.  This was definitely a good purchase  and one that I will get a lot of use out of on my travels!!
