Product is flimsy and will not fit my smaller lens, only fits larger aperture zoom but on that lens does an OK job although actual effectiveness is hard to discern

I love this little reflector! I use it for taking photos of my boys when we don't have the best lighting. I was expecting it to fit more snugly around my lends than it did, but I don't mind having to balance it a little. I appreciate that it is dual sided and that it folds up TINY to fit in my purse/camera bag easily. I would definitely recommend it for amateur photographers or if you need something super portable.

I have only used this once. Out of the box it looked great but then after I took it out a second time, somehow there is transfer to the white area from I guess the fabric on the edge that won't come clean. I will continue using it, but disappointed that the white won't truly be white after a single use.

OUTSTANDING! Love this thing. Folds down VERY compactly. I can see where the white might get soiled fairly easily, so keep an eye on that. But you can't beat it for the price. It has saved my bacon on two shoots already, where I was running and gunning a bit too fast to do the white balance. I just shot five seconds from all the cameras at the end of the shoot in the same lighting conditions, and white-balanced to that in post.

Plus, it makes a nice little reflector.

GREAT value for the money!

After reading other reviews I was mildly concerned the white section would be smudged, but it's pristine white. Quality seems great -- snappy. Edge support is stiff & sturdy feeling, but not so stiff as to be difficult to re-fold for storage in the included fabric case. Hand grip has foam padding. Silver side is a bit crinkly like unfolded aluminum foil, but should be fine for simple fill.

I compared the gray section to a new Delta 1/CPM 18% gray card, and to my eye they look identical in value and color, so I'll feel confident using it to set my camera's manual white balance adjustment.

I took a picture with the tri-panel in the middle of the shot, and the histogram gives three sharp spikes "” I can see how this would be useful to check exposure.

No instructions came with it. No instructions on the CowboyStudio website either that I could find. Consult your camera's instructions for how to manually set white balance, point at the tri-target and click. Of course it's also useful for post processing; take a photo of it in the lighting you're going to use for the shoot, then in software you can select the white or gray sections to calibrate your photo editing software's white balance to neutral. Every time your lighting changes, recalibrate your camera's white balance and/or take another photo of it to use as post processing reference for neutral/white.
