1 - this gray card is really gray - so no color cast when manual white balance 2. - to fold the card as a reflector is great - never again bend corners, there is always a place to store, protected in the enclosed bag. 3. - I like the product videos from Lastolite, instructive, informative and entertaining, 4. - The price: due to the good workmanship and quality as well as the product idea just to tolerate even a gray cardboard card from Chinese (I've been a few years) will cost a few Euros and shows in direct comparison that it mainly in the white balance problem is. Conclusion: Do you really need a high-quality gray card, there is a clear recommendation on my part.
