Review (4/5): Still fell off
The end of my hair dryer was just under the limit at which the Snozzle said it would work. At first it seemed it was going to stay tight, but when I lightly pressed the fingers into the back of my head with high heat, the snozzle came off. At one point it even came off of the diffuser. My daughters’ hair dryer has a smaller end so I’ve been using that one—works well there.
