So cool! Works great and I love that it’s collapsible and takes up less space than a big one. It does not slip off the hair dryer if you use it right. You have to twist it to make the rubber grips grab on. The only downside is it tries to collapse when i press it against my head so i have to be more gentle than I’m used to. Do measure your hair dryer first. The diffuser will only fit the specific measurements in the description. It didn’t fit on my hotel hair dryer so I have to pack my hair dryer. Not a problem for me.

By pushing the silicone diffuser as far up on the nozzle as possible you keep it from collapsing. When done this way, it works perfectly.

I used it on a cruise and worked very well! The hairdryer was a standard one that most hotels have so I’m glad it fit. May need to wiggle it a bit to stay put it once it’s on, it does the job.

I love this diffuser! I bought it as a back up for our cruise. My new hair dryer came with one but it was too small to be effective. I swapped it for this one and it worked better than my regular one at home.

Handy, works as expected.
