Doesn’t work well with the Revolution 6000i Pro Dryer [SEP] I have a Sedu Revolution 6000i Pro Dryer, and bought the Xtava Orchid Diffuser. This nozzle cannot sufficiently grasp the Orchid Diffuser, resulting in the diffuser falling off shortly after being attached. Even if you invert the hair dryer so that it and the diffuser are pointing upwards, same thing happens.
