Comments about Interfit Photographic Interfit Photographic Strobie Twin Umbrella Kit with 48" Umbrellas Stands & Brackets & Case, for Shoe Mount Flashes:

I ordered this set and discovered you can't use the silver/black stand alone, unless you want to cut off the white and ruin it. The white is sewn onto the umbrella frame.
You have to put it over the white/translucent. The pictures show the silver lining w/o the white.

After contacting Interfit here's what they had to say:

The picture is misleading. You could either use the umbrella's as the translucent only or place the black/sliver over the translucent and use it as a bounce.

So...If you're thinking you get a 3 in 1 umbrella...well you don't.
The quality of the stands and mounts appear to be failing solid.
