Not for the Black Orchid as advertised
I bought this specifically to use my Black Orchid diffuser with my Dyson, like many other reviews. Despite following the directions very carefully, after watching multiple how to videos, I still can't get it to stay attached. It goes on fine, but falls off regularly. If I'm going to have to glue something on, I'll just modify one of my unused Dyson attachments so that at least I don't also have an extra piece that makes the dryer longer and clunkier to use. Well made product and I'm sure very useful for many devices, but this was so heavily advertised for the Black Orchid that I'm disappointed in it's poor performance.
