It works [SEP] This does work. I invested in a nicer hair dryer (so worth it, why did I take decades to do this) but could not imagine living without my orchid diffuser. After trying a lot of things I found this. It does work, it stays on. It's probably a little expensive for what it is but I'm actually impressed someone decided to make some money off of the popularity of these diffusers and solve a problem thousands of us have. My real question is for the folks who make those diffusers--why on earth not make them with a longer attachment or a stretchy attachment so they fit more dryers? Lost opportunity. Regardless, glad someone took the initiative to create this product and I'm impressed and surprised it works so well.
