Did NOT work! [SEP] It's not the best! Collapses constantly and I have to actually hold it on the dryer entire time I use it...A real pain!! I have a Rusk weightless hairdryer so really don't have many options due to its small nozzle. Only reason I went with this model was bc I read in questions it would fit. I would send back, but I think I waited too long 😣. Maybe some find it useful, but I did not especially for $15.
