I recently received my ColorChecker Passport. After doing a few shoots with it I can tell you it's amazing. Setting the profile for my camera in different lighting situations to get the perfect color calibration for my camera is awesome. It so simple to use too.
I use it primarily with LightRoom. Make sure you download the DNG Profile Manager so you can manage and rename the profiles you created. So you don't have to hunt for it like I did, it's located here: DNG Profile Manager
