Vidpro WB-24 White Balance Dual-Sided Disc - 18% Gray Card with Target & Neutral White Panel - Collapsible & Wipe Clean Surface Reference Reflector Use in Any Lighting Condition Includes Carrying Case

This little target helps me get focus when shooting video by myself of myself. Just hang on a lightstand where you will be and get focus, exposure and white balance all at the same time. Great product.

I've used it to balance DSLRs and BirdDog PTZs and it works great. I didn't need a full color card for correction, just enough to get the correct temp. I also wanted something portable and large for wide cameras at the back of a room. Solid purchase.

This was the best value I could find. Also the biggest!

I bought a couple for different kits. I like how large they are for giving white balance. It makes it easier with the Blackmagic Pocket 4k which uses a huge white balance spot in camera. Also, this can double as a small white reflector in a pinch.

I tested this item against a WhiteBal card and an XRite card....both of which are tested and certified neutral, and this is neutral as well! This was actually a surprise since I have purchase other inexpensive white balance cards from Amazon only to find that they are nowhere near neutral, rendering them useless for setting accurate white balance. I did not expect much from this item given the price, but I am quite happy with it. Good product!

This gray card works very well. It's fairly easy to fold. The metal frame inside the material does sometimes want to twist. Other than that, it allows me to white balance very well. The price is affordable too.

I had fun trying to close it the first time because I couldn't lol 😅.... but I figured it out, be sure to twist it and it folds in on it's own, sort of.

For being marketed as 18% gray, the intensity of this gray is inaccurate. Compared to X-Rite Macbeth chart, this is closer to N35 tile than N5. This means the screen is closer to 10% gray in linear, which has cause more frustration and headache than I was hoping for. Don't use this screen for calibrating CG elements.Gamma corrected sRGB values are approximately 85, 85, 85 (closer to 33% than 50% gray) or 0.09, 0.09, 0.09 in linear sRGB.I also agree with other reviews that it never unfolds flat.

Quality control was a bit slack, received a damaged item.
