Croc Magic Diffuser

This diffuser is really cool you can turn it so that the hair only goes through the pointy things or change it so it goes through the vents. I got the Croc Greenion Dryer and it doesn't 'fit' on there. It will stay on but it doesn't snap on or anything so it makes me nervous that it will fall off and break, especially since the plastic the diffuser is made of is really thin and cheap so it will most likely break if dropped.
