Review title is Not all it's cracked up to be! [SEP] Got the diffuser, it fit on my blower....yay...right?  No....when the silicon heats up it becomes quite floppy and doesn't hold the diffuser's "cup" shape, so it doesn't hold your hair up whilst you are trying to diffuse it.  It was flopping all over.  Waste of money, more hassle to send back, so lesson learned.  A hard plastic "cup' with a silicon ring to fit different blowers would be a better idea.
