Review (4/5): Great travel companion!
I purchased this for travel after I burned a hole in my mesh fabric ion diffuser. I liked the fabric one because it was the size of a sock, easy to pack, and the elastic neck could fit any size dryer nozzle. BUT, if you don't maintain enough distance between the end of the nozzle and the mesh, it burns! So, I bought is collapsible style for a change and it's awesome! My hair dries quicker than the fabric style, and it's much closer to the diffuser I use daily at home. The only complaint I have is some hotel dryers have nozzles that are too wide to fit the neck of this diffuser, so now I travel with both styles so I have a back-up, depending on whatever dryer is at the accommodations we're at. It's still way lighter to carry both types than traveling with my own hair dryer.
