Query: Beware...

I was looking forward to having (from what I had heard) a very good calibration system. Well, after installing it and running the calibrater it rendered a VERY magenta cast to my calibration. I tried everything to correct for this problem. After a couple wasted hours I came across the FAQ on Pantone's site and come to find out, it is much more common than they would like to admit. I submitted several tech support emails and have yet to hear back from them. I am returning it back to Amazon as defective product and let them deal with it. Don't buy it...spend more money or rely on your own eyes for a much more accurate rendition of color!
