Jul 13, 2010 - well, i think i need to learn how to use this. great for roots, im having trouble with the rest of the hair though. i have to do like another poster and use it for roots and finish with a regular diffuser.but, i would like to say to the posters who have trouble keeping it on the hairdryer. i did also, it kept popping off until i took the rubber piece inside the adapter off.(the piece that keeps the "teeth" so tight.) it works great now and is tight as can be but doesnt fall out.
