does not fit ALL dryers [SEP] purchased this for my daughters thick curly hair. even though it comes with different rings this does not fit my dryer and the metal adjustable clasp is hard to use even with a flat head screw driver. I'm pissed i spent $16 on this piece of crap and now i have to buy a blow dryer that actually comes with this piece to be sure it fits. what a waste of my money and the time i spent being frustrated trying to get this crap to fit! feel free to insert more appropriate curse words to fully grasp how pissed i am!
