ColorRight or ExpoDisc? Do they work?

Is there anybody who uses ExpoDisc or ColorRight to get correct white balance?
Does it really help you to save time during post processing?
I have read all the reviews but some of them are there to sell the product rather than telling us how useful they are...
Thanks,

I've only had experience with the Balens WB cap, I like them a lot, custom white balance is easy to set, but I wish they were cheaper.

I have the ExpoDisc. I find it useful for tricky lighting situations where the lighting is mixed (e.g., combination of incandescent light and sunlight). It works great... basically you take a test shot with the device attached to your lens and use that as a custom white balance. The whole process takes about 1 minute or less. Some say the device is expensive, but if you use custom white balance, it is an efficient way to get it right in camera and avoid a lot of post processing.

I find a simple neutral gray card MUCH simpler to use and far more versatile than any of the ExpoDisc type units. I can use a gray card to set up a custom white balance or I can merely put it into the scene for a test shot, allowing me to have a reference when I am converting RAW files. A neutral gray card is not only far more versatile than the ExpoDisc but far less expensive.

had the opportunity to try both. gray card is still the simplest for workflow management

They do work, but I find the Expo disks results can be emulated pretty much exactly using a Melitta white coffee filter.

I noticed that on the latest packages, they put the color balance information right on the bag.

I have an Expodisc, and have used it very sucessfully in the past, especially for mixed light situations. Contrary to the instructions, I find I get the best results when I put the ExpoDisc over my lens and just take a shot in the direction of the light source(s). Ie, in a gym, I'll hold the ExpoDisc over my lens, and shoot towards the ceiling. then set my custom WB from that.

However, I got an X-Rite ColorChecker passport for Christmas, and I've been using that pretty exclusively lately. I love the color chart, and the 2 rows of creative WB adjustment patches.

Have been using a WhiBal card and sold my ExpoDisc. Much faster and easier to use in my opinion.

I'm debating the Whibal (the stand is pretty cool) digital grey kard, and the photovision stuff. I really can't decide. The photovision is cheap and small (6") so I'm leaning that way. All seem to have their merits.

I have both a whibal and an expodisk. They both work great and you spend a lot less time color balancing. The whole value that you are paying for is the color balanced and tested color fast on both.

for single point source of light, I like the ED better - i.e. sports. For complex lighting, like say, a flourescent lit with side natural lighting then I like the whilbal in a test shot better.

Thanks guys!!!

WhiBal is only good for WB...it is too bright to be useful as an 18% gray card (equiv. to using an incident light meter to read light falling on scene). Products like PhotoVision, Kodak gray card, Douglas grey card all can be used for both WB and for exposure metering (if you have a one degree spot meter to read the tiny sample patch for exposure, so can the X-Rite ColorChecker)
