I love the idea of a collapsible diffuser so that I can travel with it. However, when it came to actually using it, it kept collapsing on itself. I like to use a diffuser closer to my head to build more body but it kept folding back up. I managed to use my free hand to hold it but was disappointed in that feature. For future models, maybe a locking device that will hold it open when being used?
