very good
does what it is asked to do, I have however had black screen issues (graphics card crashing) with an AMD RX 6600, (of course, updated drivers etc...) something I don't have with an NVidia card, I need to test calibrate with another version of profile to see what it gives, but it is to be taken into account if you have an AMD card
otherwise, the calibration is very simple to do, the software guides us very easily and even the most novices will get through it very easily, it is for me one of the most important purchases to make when processing photos
