After all of our years in business, we realize that the only place you can save time and increase income is getting to a good color blend as soon as possible. We use the color coach pro or the spectrophotometer as a coach on the sideline for every job we do. If this great technology gets us to our color even 20% (that is an extremely low estimate) of the time each week, look at how much time I have saved due to hi-tech technology. I would be retired and on a beach somewhere if I had this type of technology over all the years I spent matching colors.
