What is everyone's impression of this product? I dug through the forums and there are not a lot of discussions of it outside of when it was released. Anyone using it with great results? I was going to pick up some Whibal cards but this has been on my list of products to possibly get.
I shoot a 3 year old exploring the world 90% of the time and do not bring a lot of gear outside of my 7D and occasionally my 580EX II. In some really difficult lighting situations I will do a custom white balance (not off a white card, just off something I know is near white in the environment to get it close). I have had very bad luck with gray cards in general, they never seem to work well when using the color picker in LR. I've had much better luck using custom white balance in camera when AWB is really off.
I want to start shooting more consistently though and want to tweak white balance in LR a lot less.
