When shooting with flash you may have observed sharp shadows or bright highlights on people's skin. Those are both caused by the flash being close to a point light source[a]. Point light sources give rise to sharp shadows, since, as seen from the shadowed object, the light source is either completely visible or completely hidden. They also result in very bright highlights for the same reason - either the beam bounces completely back to the observer, or it doesn't. A flash diffuser alleviates this by expanding the area the flash beam originates from, and therefore the different angles the light strikes the object.

After being the unofficial official photographer at a friend's birthday party and spending too much time Photoshopping out specular highlights from people's foreheads and cheekbones I decided I needed a flash diffuser. Most diffusers were built for standard flashes, but I finally found one that would work well with just my popup flash: The JYC P9 Flash Diffuser[b], being both cheap (49 SEK / 8 USD) and easy to carry, was a given choice.
It looks very similar to the Gary Fong "Puffer"[c] flash diffuser, but has only five instead of seven mounting holes in the screens. This limits the amount of vertical adjustment you can do with it by about a centimeter in total, but I found that I wasn't even close to the extremes when mounting it on my D40.
1. The Kit
What is included in the kit bag then? Mine came with this: A mounting bracket and three screens.
There has been a number of complaints about the Puffer, saying that it breaks easily. In contrast, the bracket that JYC ships is a fairly solid piece of plastic - as far as pieces of plastic go, anyway. I had no problem plugging it into the hot shoe of my camera. Attaching the screen, however, turned out to be a bit more difficult. The screen simply has five holes and is held in place by friction against the plugs on the bracket - and when I had to push the bracket into the screen I was really afraid I might break something. It required some force. Separating the two is also not a simple operation. When mounted the screen sits in front of the pop up flash:
3. Light Loss
Due to the way the screen works by refracting the light from the flash, there is some light loss. I can, however, report that when used in summer noon sunlight with a 200mm lens, from about three meters away, there is still enough light coming through the screen for it to be comfortably used as a fill flash. I even had to set flash power down 1 EV to not blow any highlights.
4. Sample Shots
Being a cheap sucker with a thing for not spending that much effort in doing test shots, I brought my D40 and a 55-200 lens to lunch with T and blasted away while he was eating. The results won't win any photo contests, but they show the effect of the diffuser. These were all taken at 55mm, from a distance of a little less than one meter.
The colored diffusers change the color of the flashlight (duh). It is really a matter of taste here - I think the neutral diffuser is the way to go, but some prefer the orange, which I think makes the person look like an Oompa-Loompa[d]. Maybe the flash compensation needs to be set even lower to avoid affecting the well-lit portions of the subject. These shots were taken at about three meters at 200mm in bright noon light.
It really works. While I have no doubt that one could spend a lot more on a proper flashgun and so on, the JYC P9 really does deliver image improvement above and beyond its low $8 price. The downside is that you have yet another thing to haul around with the camera, but one can really not accuse the P9 of being bulky.
Name removed because these are some damn unflattering shots.
