Willie Morrow's Unbreakable Thermo Blow Dry Nozzle [SEP] Very very heavy, hard to attach.  This is supposed to be able to be used for any type of blow dryer. I had a bugger of a time attaching it to my blow dryer. In fact tried it on multiple ones that I had.  This one needs to be made a lot lighter or your arm will fall off using it and like I said a real bugger to attach.
