It didn't work
I was so exciting to get this and had read rave reviews, however, it didn't work. I used the SnozzlePro to attach my Black Orchid Diffuser to my existing blow dryer. In fairness it may be that the Black Orchid Diffuser didn't have enough grip space to hold the SnozzlePro to the blow dryer. Epic fail, the diffuser kept falling off, a lot. I ditched the SnozzlePro and ended up buying the blow dryer that was made for the Black Orchid Diffuser.
