Review (5/5): Great product
UPDATE: 2 years later and this beast is still kicking. It does occasionally slip off the end of my hairdryer, but that because of the finish of the dryer, and super small barrel - not the nozzle. I've gotten my money's worth from this 20x over. Don't waste your time with cheaper versions, this is what you want.
I don't understand the metal bar - and mine also popped out, but it is otherwise a wonderful pik.
