Good for travel but not especially sturdy
This diffuser is lightweight and only 1.75&#34; tall when collapsed. And the part that slips over the dryer nozzle stretches ever-so-slightly to accommodate my Conair Vagabond, which has a non-tapering barrel and 2&#34; mouth. I don't mind that half the vents in little circular piece (in the center of the &#34;bell&#34;) are blocked by plastic; it's a minor flaw. But it gets annoying when the diffuser keeps collapsing, partially or fully, with little pressure when I'm drying my hair.<br /><br />Despite the collapse issue, I bought a second diffuser about a year ago to use at home. It was better than the bulky plastic &#34;universal&#34;  one that kept falling off my full-size dryer. Since then, 5 of the 6 larger nubs have broken - the bullet-shaped caps came loose and fell off. I just bought a replacement - but not by The Curly Co.
