The software installation is fast and easy, no problem. Once done you plug the small device to PC or Mac via USB. The software is started and the following handling to do that is very simple.
The receiver is placed in the middle of the screen and allowed to color calibration. It takes about ten minutes and when everything is over you are shown the difference of the screen before and after and there, we see the change. The work is finished and you have almost nothing, it's great!
For me there has been a great difference because when the screen is the same rule is no mark if not his vision.
It is a device that I consider good for those wishing to have an image that actually correspond to reality, by that I mean amateur photographers (who wish to have the same colors on the screen than on their APN) or for Other applications or the color is very important!
It is a bit expensive but against is handy!
