I bought one of these about 6 months ago. The problem with it is that it can't give you the information to go have paint custom mixed it only gives you 4 or 5 close matches from different paint companies. The yellow it suggested for the mario cabinet was close but none of the street fighter playfield colors were. It was useful for getting rgb values to use for making score cards with colors that closely matched the game. For wall paint it was able to match all of the cans of paint I had lying around but none of those are custom colors. It's now collecting dust and I still had to mix my own paint.
