Review: Works as it should. - Works as it should. Easy to use.
Review: Great addition to a great modifier... - A great option for any 7 foot parabolic umbrella. I bought one for each of mine Westcott 7 foot umbrellas (one of which is silver and the other white). You will lose perhaps a stop of light, but the cover turns your umbrella into a massive soft box. The opening in the center of the diffusion cover is big enough to allow my Alien Bees to fit through. Here's a tip for mounting the cover - don't try to put it onto an opened and mounted umbrella (your arms won't be long enough to reach both sides). Instead, take a closed umbrella and insert it through the diffusion cover opening with the tip of the umbrella pointed toward the floor. When the umbrella is completely past the opening, reach in with your other hand and open the umbrella slowly. The edges of the umbrella will apply even pressure to the elastic band on all sixteen sides as it opens and when locked open, the diffusion cover will be taut all around.

### ⭐⭐⭐⭐⭐ Excellent
*by M***N on April 27, 2015*

Stretches over umbrella very easily - was surprised. It creates a 7-foot softbox. But when you fire your strobe there will be a hotspot where the strobe fires though. Comes out hot in the center. Just though maybe I could use my long-throw reflectors on my White Lightnings, and maybe that would get rid of the hotspot. Botton line is that it's brilliant to have this cover, because without it, you still get harshness reflecting off the inside of umbrella. With it, everything is softer. One thing I got using it was much more magenta in my portraits. It tends to warm everything up for some reason.
