Convenient for situations when normal equipment is not available
A simple way to diffuse the light source to reduce harsh lighting. Also help to wrap the light around the subject
Has to be stretched a bit as the instructions state, however after initial stretching fits onto flash fine.
Pops onto the flash easily and provides a nicely diffused output.
For wonderful even lighting, bounce, fill, portraits, you need this, the opaque model. I've been experimenting outdoors with the gold model and have found some interesting uses. You would have to decide on whether it was for you. The opaque is great. I use the model for the Canon 580 EX II.
I started using the omni-bounce recently and it seems to work fairly well. As a novice to photography I have to think about the position of the flash a little more with it in place. There is far less affect even when the flash is at 45 degrees. Otherwise it is still a good product.
I like using it - as the 580EXII can be a tad harsh it does well to soften the shadows and impart a somewhat more natural appearance to the highlights on people faces and other objects which require a little bit of added light. It stays on my flash most of the time for indoor shots.
I haven't tried all of the other products that claim to soften on camera flash, but the Sto-Fen Omni-Bounce works for me. It is small, easy to carry, and it works better than direct flash.

Great in a small room having a white reflective surface to bounce light off of the walls and/or ceiling. Otherwise if you don't bounce the light with this, you won't see a difference in most other applications; will look the same as bare flash as light is just dispursed everywhere. Softens shadows on subject nicely.Keep flash at 45 degrees (or 60 degrees) to get best results while bouncing off white/reflecting wall/ceiling. I have noticed the flash does have to work a little harder so a little more juice is required, but results are worth it. Performs up to expectations and definetly recommended if you're going for the effects it accomplishes.Asim [...]
Great for softening flash, easy to put on but a little more difficult to get off.
I've been using this product for a couple of days. It's not a bad product at all. It is what it is and does what it's meant to do. It does diffuse the light from my 580EX nicely. I'd recommend spending the extra money on a LightSphere II
