UltraBounce: Bare Bulb Flash, Flat as a Pancake
Mind you, these things are not panaceas. No matter how much you pay (some will cost you a ridiculously Scary Song) their primary use is to send your flash's light out in all directions.
Sure, if you are in a small room, you'll get some fill bounce from the ceiling and/or walls. But it would be a "Whale of a Tale" to attribute any other magical, wallet-draining powers to them.
So, what are they really good for? Omni-directional light, of course. Off-camera, these things are quite useful. The original L101 post on bare-bulb modifiers is here. A B-B mod (a Sto-Fen) was also used to light the alcove for Michael in Paris.
Given that they take up no room when folded, I'd swap out my four Sto-Fens for these things in a New York Minute if I were concerned with cubic inches when traveling.
