Installed my DDM Slim HID kit this past weekend. So far so good. I can't believe how small the ballasts are. The bulb color (they advertise 4500K) are indeed OEM-ish color. Both bulbs haven't flickered upon startup although one side is a teeny shade off from another. I'd say they're about a 95% match. Can't really tell unless you stare at them for a while.
