Sounds like a great idea, but be aware that the term "universal" is a misnomer. It's not as stretchy as I expected from some reviews and didn't fit any of the hair dryers in our house. Since it seems impossible to upgrade the diffuser, I ended up buying a new hair dryer just for this diffuser! :) I travel a bit so I really wanted this to work. I'm still considering returning it, but with a perfectly working dehumidifier it seems so wasteful to swap it out just to get the right diffuser. I've noticed similar silicone diffusers under different names, but the design is exactly the same except for the colors and it's not worth trying another brand as you'll encounter the same issue. BTW I've seen other people comment on this, and I also have an old model Ion Shine Conair tourmaline hair dryer with two side vents that never seems to have had a diffuser. But deflectors aside, the nozzle is still too wide for this diffuser!
