best color change yet!
i've been using NYOS for awhile now, since they came to this side of the pond. at first i was intimidated by the amount of components but that quickly subdued. right off the bat i noticed how bold the color change is. and talk about precise! within 2 small drops it goes from starting color to target color. im never guessing or have to round it off to the next color on the wheel. highly recommended for accurate and clear readings.
