This is the most frustrating product I've ever met. First of all, it's an excellent foundation. Gives medium-full coverage (depending on the number of layers), stays put all day long, hydrates dry skin, but also works perfectly on normal (not so dry) parts. BUT: As others have already mentioned before me, you'll find the shade range is very poor if you're not Asian. I used the Dual Balancing foundation from Shiseido before (it's discontinued now), and found a match in that collection, but it's impossible for me to use this one. The I range is supposed to be neutral, but it is yellow. The O range is supposed to be yellow, so I didn't even look at that. The B range is pink, OK, but very dark. If you're neutral or cool toned, you're chances are very minimal for a good shade. Some people don't care, and choose the one that is closest, but there are a lot of good foundations out there, and a perfect shade is very important for a flawless look.
