Review (5/5): I'm so glad I bought this thing!
I love the SnozzlePro! It holds my Xtava Orchid diffuser securely without fear of it falling off.
I like to use the Manes by Mel 'hover-diffuse' method for my curls, but i COULD NOT keep my diffuser from falling off. I hesitated to buy this for a while because of the price after shipping and everything, but it is definitely worth the money.
I did give "easy to use" only 4 stars because it was a little difficult to get on, but other than that it's great!
Just for reference I have the Conair 1875 hair dryer.
