Has anyone used Flip-it! diffusers?

Wondering what people think. Seems to be a few people out in different forums who favour this diffuser more so than the Sto-fen as a budget option.

They work differendly, you have more controll with the light with a reflector.
Diffusers throws the light in all directions and relies on that light bounce off off something to soften, this work well in homes but i tend just to bounce it off the ceiling without a diffuser.
With a reflecor you catch some off the light and reflect it on the subject, you can vary the amount of light with the angle. Indoors you can balance the light that comes from the reflector and celieling to get a good result. Outdoors it also work pretty well because the bounce card is higher up then normall flash so you get a more natural effect.

I'm no expert on this so hopefully i'm correct on most things

thanks, the flip-it does seem like a good option, and reasonably priced, and compact for the camera bag. When I get my flash and start using it in anger I'll see whether I then find something more is needed.
