I was able to do the calibration on both of my monitors and printer, however, the text in the program isn't easy to read. It's not scaled correctly with the text being either overlapping other text or being cut off. I tried changing monitor resolution, but it didn't help. The program came on a DVD which I don't have, so I had to find it on their website. It took a couple tries to get it to install correctly. IMO, all of the color calibrators are overpriced for what they do.
