This diffuser is not universal but it fits my travel dryer perfectly - which is why I bought it.  I have a small travel dryer with a narrow nozzle.  This fits fine.  I tried it on the dryers in the hotels of my last two trips.  It did not fit either of them.  I heard a complaint about it tending to collapse.  It will do that if you push it on your head but holding it lightly on your head or just off your head it is fine and works just fine.  I have curly hair and am pleased with the performance.
