Colorblind Prove it! win V4.0 and the colorblind Sequel Imaging Chroma 4.
There are still many rebranded Chroma 4 colorimeters for sale out there today, it's a pretty good device and I have been using it for years. the Software is fairly easy to use and quite good. I just bought a second Xrite package and won't be using it anymore.
All I have is the CD and the colorimeter, no box etc. Instructions are easy to follow once you install the soft and there is a plethora of help online if it's your first effort in calibrating your display. In my opinion this is a better start than some other cheap options in fact until recently it has been used at some of the online printers to calibrate their displays for printing to wide format printers.
