Yes. I have a 5"x7" model that I use for macro photography. They can be quite effective at creating a more diffused, softer lighting. Here are a few examples. You can also make your own as a DIY project

Yes, they work for what they are intended. As LoneRangeFinder indicated, these are great for close/macro work. For people, they are only a marginal improvement over the bare flash if you are say, 10 feet away.

Remember, what makes a soft light is the size of the source IN RELATION TO THE SUBJECT. So for that insect in the previous post, that diffuser would be like a 15 foot by 15 foot softbox for a human. (Maybe bigger!)

So this is a slight improvement over the bare flash - but not a lot.

I use these for SOME diffusion.

Are you asking about that particular model (which is quite small), or about softbox diffusion in general? And for what type of photography? As LRF mentioned above, we macro-photographers use softbox diffusion for even subject illumination & harsh shadow elimination.

I use that very softbox, but not on a flash unit. I find they are indispensable on a lightning trigger to narrow the field of view of the trigger to make it comparable to my lens. The triggers have a 180 degree field of view, the lens I like has a 60 degree field of view. Adding this softbox keeps me from getting hundreds of black images when the lightning strikes in front of the camera yet outside the lens' field of view, they are very good for this purpose.
As for use on a flash? They work, but I have found them to be less translucent than other options and absorb a bit too much of your light because of it, almost like using a double diffuser.

Looks like a knock-off of a Lumiquest Mini Softbox. I wonder about the quality of materials.
