I purchased a Devachen Defuser online as the Devachen website says it is universal and fits all dryers. Be warned. It did not fit my Revlon, Conair, or travel dryer. I think the only dryers it might fit are the $100 plus ones. At $45.00 this little hand defuser was one big rip off. If any of you have one of these defusers, and use it with luck,could you please let me know which dryer you use?
