High expectations... [SEP] I just received this today after seeing a youtube where a woman talked about packing one but I'm a little skeptical.  I need a diffuser for travel but this doesn't fit my normal dryer so I'm very hopeful that it WILL fit dryers I come across in my travels.  We do strictly carry-on luggage and there is no room for my bulky dryer so I really hope this works!  It does compact nicely for packing and it comes in its own little cotton bag.  Fingers crossed this wasn't a waste of my time and hard earned dollars!
