Review (2/5): Meh. It kept shooting across the room.
The attachments didn't really fit my dryer. The diffuser would pop off and either fall to the ground or go shooting away. When my old Conair dryer died (from old age--through no fault of the diffuser), I bought a dryer that came with a diffuser that was made for it. Problem solved. I'm giving this diffuser set away. Maybe it will fit someone else's dryer. I'm going to save my money in future and buy either dryers that come with their own diffusers, or diffusers that are made to work with a specific dryer.
