Review (3/5): Not universal
I have a pretty basic blow dryer. It's a standard size. I cannot for the life of me get this on my dryer. Also I know a lot of people buy this specifically for the Dyson and the Black Orchid diffuser. I ended up returning my Dyson but still wanted to use this on the Black Orchid and my regular dryer. The diffuser doesn't have enough surface space for this to really get a good grip and stay on. And it's a pain in the butt to put it on over and over. I don't know how y'all are doing it.
I'm keeping it because I don't have a printer to print a return label, but I would really like to return it since I'm not able to use it.
