The eyeone display pro device is a much more accurate device for the money. It is designed to calibrate displays as well as projectors, and is not an all in one device like the colormunki, which seems to have many design elements that while are good for versatility and economy of price, it is not so good for overall accuracy, particularly when calibrating displays.
