Camera Trax 24 color card review

I have some more product photography to do soon so I thought I would finally go ahead and get control of color once and for all.  I've been shooting RAW and using a grey card for a while, but I have also noticed that some reds seem to come out magenta to my eye.  Now I realize that to know for sure I would need a calibrated monitor, but prints and other monitors confirm the problem (as well as the RGB values)
